Barcoding indigestion
For retail purposes, barcodes facilitate grocery checkout, but the barcoding of groceries was
never intended to substitute for ingestion, digestion and assimilation.
Similar considerations should apply to genetic barcoding ("Barcoding
life," March/April 2007).
Barcoding of DNA, and related compilations of genetic codes, has the potential to make enormous
contributions to biology if used in conjunction with other approaches. Genetic code information
might help unravel taxonomic puzzles. For example, barcoding of recently ingested food materials
might be used to investigate the feeding habits of small soil invertebrates. In addition, barcoding
of DNA might facilitate biological surveys by making it possible to identify material at life-cycle
stages that can not be identified by traditional means; e.g. insect eggs, moss gametophytes or fungal
mycelia. But the idea that barcoding can entirely displace the need for traditional taxonomy is
simplistic to the point of being destructive.

Haida and the land
Haaw'a, thank you, for your photo sketch of Haida Gwaii ("Keepers
of the forest," March/April 2007). In few words
and great pictures you captured a great deal about this magical place.
Three and a half years ago I "retired" to Haida Gwaii, somewhat anxious about isolation. I am delighted
to find that I am as busy here as ever I was in any city and happier in a vibrant mix of cultural communities.
I too am trying to learn the Haida language from some of the elders you photographed, each one a precious source
of their nearly-lost cultural heritage. Mildly put, it's a challenge — and a great privilege and much fun.
It's time we recovered before it's too late that Haida respect for, and intimacy with, the land and oceans that
give us so much. Living here we have the potential to demonstrate ways of living sustainably with each other and
with our environment.

Protecting my heritage
I am a Nova Scotian whose roots go back 250 years in Lunenburg County, and I presently live in Cape Breton.
I was horrified to read of the plunder of Nova Scotia's shipwreck heritage — my heritage — in Heather
Pringle's article ("Finders
keepers," March/April 2007).
I am also an ecologist and a scuba diver. I fail to understand why our shipwrecks and associated
artifacts and, more importantly, the archaeological information they contain, are not better protected.
Thank you for bringing this to my attention. I intend to distribute the story to other concerned, ethical
divers and to pursue this issue with my elected representatives.

As one of the people interviewed for the treasure hunters article
by Heather Pringle, I want to point out important facts that
were omitted.
A private company, Offshore Diving and Salvage, located remains
from the Auguste in 1977. Robert Grenier and his team from
Parks Canada had previously searched the same area using an
array of sophisticated electronic equipment and had come up
empty. This was not the first time that Parks Canada had searched
for shipwrecks funded with our tax dollars and found nothing.
After the Auguste was discovered by Offshore Diving and Salvage,
the company soon found itself in a joint venture with Parks
Canada. Offshore Diving and Salvage contributed its fair share
of time and money toward recovering the more than 4,000 artifacts
that are now in the custody of Parks Canada. Yet the company
has never been publicly acknowledged by Parks Canada, and
those artifacts have never gone on display to the public.
It's no secret that Parks Canada's underwater
marine archaeology unit has been totally absorbed and obsessed
with the Red Bay project in Newfoundland and has virtually
ignored the thousands of shipwrecks in other parts of Canada.
The unit's solution for the remaining shipwrecks in
Canada is to try to gain control by promoting and endorsing
the flawed unesco Convention on the Protection of Underwater
Cultural Heritage. This convention will never come into effect
in Canada or even in the United States simply because it serves
only the interests of the few. If you read the document in
its entirety, they will see that it favours government-funded
and -sponsored marine archaeologists only and does not allow
any place for involvement from the private sector.
The Canadian Geographic article is a glib portrayal of Nova
Scotia's Treasure Trove Act. While the article briefly
touches on the 90 percent split, very important facts were
left out. For example, all non-treasure-trove artifacts automatically
become the property of the Nova Scotia Museum. They must be
catalogued, recorded and conserved by the salvage company
at its expense and recovered under the terms of the excavation
permit. The salvage company is allowed to keep only 90 percent
of the actual treasure and does not even get to choose what
it can keep. The Nova Scotia Museum and the Maritime Museum
of the Atlantic get first pick.
Many successful salvage projects have taken place under the
Treasure Trove Act, and the Nova Scotia Museum and the people
of Nova Scotia have received thousands of artifacts and hundreds
of gold and silver coins from shipwrecks such as Le Chameau,
the Auguste, HMS Leonidas, HMS Feversham and HMS Tilbury.
However, to date, less than one percent of these artifacts
have gone on display. Why is this? Why do Parks Canada, the
N.S. Museum and the Maritime Museum of the Atlantic dedicate
precious little time, space and resources toward shipwreck
displays, but have an unlimited amount of space for storage?
They seem to have all kinds of resources for other projects,
yet they have not hired a full-time marine archaeologist.
Regarding statements made by Jonathan Kyte, the marine archaeologist
subcontracted by Deep Star Exploration, he arrived late — one
week after the official project start date. That was his fault,
not ours. When he did arrive on site, we were laying out buoys
and setting up grids. We were also conducting sweeps and running
search patterns with underwater metal detectors. For the record,
nothing was recovered or disturbed in any way by our team
without a marine archaeologist being present.
The article states that "in anticipation of a big find,
Dwyer and his associates had already outfitted their chartered
boat with a costly lift and large compressor so that they
could begin raising artifacts immediately. The atmosphere
on board resembled a scavenger hunt." The project dive
boat was outfitted with an air lift for uncovering sand from
any target areas. This is standard excavation equipment. The
metal detectors frequently registered hits that were as much
as a metre below the sand. The dive team was professional,
organized and experienced. Our search was scientifically conducted
under the direction of the senior project marine archaeologist.
If it weren't for private-sector salvage companies,
many wrecks would never have been discovered, let alone salvaged.
Shipwrecks are no good to anyone on the bottom of the ocean,
as less than one percent of the public can scuba dive. Most
Canadian museums, as well as Parks Canada, would have very
little in their collections if it weren't for the private
sector.

Peat and repeat
I read with concern in "The
inside story" ("The ring cycle," Jan/Feb
2007) that peat extraction is turning
"once thriving peatlands into fields of
clay." This is incorrect. The Canadian
peat industry has a preservation and
reclamation policy which requires that
a thick layer of peat be left on fields
when harvesting ceases. Our industry
now restores or reclaims nearly all the
bogs that have been harvested.
The restoration techniques we use
were developed through extensive
research by Université Laval and other
universities and were funded by the
industry. More than $3 million has been
invested and, using the techniques developed,
several hundred hectares have been
restored. Canada is now a world leader in
peatland restoration. You may recall that
you published an article in your July/Aug
2004 issue entitled "Our lady of the bog"
which describes this research.
Gerry Hood,

Heather Pringle's article is a good, balanced account of
the controversy over the Treasure Trove Act here in Nova Scotia.
However, despite the subheadline that says the rush to salvage sunken
riches has "historians fuming," she appears not to have
interviewed a single historian. I have myself interviewed several
of the people she mentions, but none of them is a historian. Having
done archival research — and given a lecture at the Maritime
Museum of the Atlantic on HMS Fantome — I want to rectify
the statement she makes in the sidebar "Legend of the Fantome."
There is no "legend" of the Fantome, except as a fantasy
among divers here, and what it purports to say is historically wrong.
The Fantome operated in the Bay of Fundy the whole of 1814 as a
tender providing provisions from Saint John, N.B., to Maine, whose
Down East coast had been captured by the British that year. Her
log states that she was "moored in St. John's Harbour" on
Aug. 24, 1814, when the White House was burned by British troops.
Furthermore, HMS Tonnant, a double-deck, 80-gun ship of the line
and flagship of Vice Admiral Sir Alexander Cochrane, would have
been chosen by the Royal Navy to convey back any White House treasure,
not a small 18-gun brig, such as the Fantome. Indeed, it was the
Tonnant that brought back Cochrane and the body of Major General
Robert Ross after the attempt on Baltimore on Sept. 11, 1814, arriving
in Halifax on Sept. 28 together with several other large Royal Navy
ships. It is simply a phantom to suggest that Fantome was carrying
treasure from Washington, of which there was none. By dignifying
this fantasy as a "legend," Canadian
Geographic is perpetrating
a media myth. It may be delightfully tantalizing to treasure hunters,
both actual and vicarious, but surely historical truth should take
precedence over popular humbug in such a beautifully published magazine.

The stories about the vanishing cedars of Haida Gwaii ("Keepers
of the forests," March/April 2007) and the treasure hunters
at work in Nova Scotia ("Finders
keepers," March/April
2007) make it abundantly clear that, as a society, we want to make
the next pickup truck payment, buy the newer dishwasher or pay down
the latest bank loan more than we want vibrant cultures to remain
intact and strong. That's a pretty sad indictment of what
we value as a nation. Once these cultures and histories vanish,
they are gone forever. Period. And all for a few more zeros in the
bank account.

In the article "Finders
keepers" I noted a photo of
the ship the Agnes G. Donahoe sinking in New Brunswick waters in
1913. That ship was owned by my grandfather, James Donahoe of Halifax,
and was named after his daughter Agnes, who became a member of the
Sacred Heart Order of nuns. Her sister, my mother, Geraldine, had
a ship named after her as well. My grandfather was an enterpreneur
who had a number of business interests, including whaling and sealing
vessels.

Nova Scotia's callous disregard for its archaeological heritage
comes as no surprise. We saw the same attitude on land.
A few times a year, on our way from Ontario to Halifax, we entered
Nova Scotia at Amherst and watched with interest as a group of volunteers
excavated a fort on the plain behind the Tourist Information Centre.
They traced old foundations, raised berm defences, erected stockades
and built replica workshops and barracks using period hand tools
while dressed in period costumes. Cannon were placed at the berms.
An information centre was built and featured a model of Fort Lawrence
made from drawings found in England. Clothing and artifacts were
placed on display by families who had held them for generations.
For our three children, this activity added colour and relevance
to their studies of Canadian history.
Then, on our trip in September 2004, we found to our amazement
that the whole site was gone. The buildings were missing, the berms
had been bulldozed and the cannon were grouped at the front walk.
The interpretative centre was closed and bore no signage about the
fort. Upon inquiring at the Tourist Information Centre, we received
vague replies from staff, with eyes averted, that the artifacts
had been removed because there had never been a fort at the site.
Researching this claim, I learned that an Acadian village had been
burned by the French and that the inhabitants had fled to New Brunswick,
where many had perished in winter. The British then moved in and
built Fort Lawrence, which was occupied from 1750 to 1755 and then
abandoned.
The extraordinary destruction of so much volunteer effort seems
to be an Orwellian effort to deny history or, perhaps, a desire
to develop the site commercially. The victims are heritage, Canadian
awareness and truth.
My family has not returned to Nova Scotia.
Garry Marnoch
Pontypool, Ont.
(Editor's note: According to Linda Brown, secretary of
the Fort Lawrence Heritage Association, the site was bulldozed
because the association was unable to obtain government funding
to keep it open. She says she was one of the volunteers who worked
on the fort and was sincerely disappointed by its loss.)
Policeless in the passage
Does Canada have the ability to demonstrate sovereignty ("Policing
the passage," Jan/Feb 2007) in the Canadian Arctic? The answer
is both yes and no. At present, Canada has absolutely no capability
of maintaining an all-season marine surface or subsurface presence
in the Canadian Arctic. Some years back, when this country decided
to purchase diesel-electric instead of nuclear-powered subs, it
forfeited a subsurface presence. When Canada decided to scrap the
building of the Polar 8 icebreaker back in the 1980s, we gave up
any hope of maintaining a strong, all-season surface presence in
the Arctic.
Canada's two Arctic-class icebreakers, the CCGS Louis S.
St-Laurent and the CCGS Terry Fox, are beyond their designed life.
Canada has all but abandoned its major shipbuilding industry, and
its ability to build replacements for these two vessels diminishes
yearly. All is not lost, however. While we can no longer compete
with the heavily subsidized shipbuilding nations of the world, we
can take a bold step and have our heavy Arctic-class icebreakers
built abroad and delivered to us at a fraction of the cost and time
of having them built in Canada.
The stakes in the Canadian Arctic will be huge in the not-too-distant
future. We must not rely on the international courts to protect
for us. We need to show some initiative in protecting ourselves.

Bear numbers
I read with interest Ian Stirling's concerns about the polar
bears of western Hudson Bay ("The
inside story," March/April
2007). However, before spreading too much gloom and doom over the
fate of the polar bear, please refer to Nunavut biologist Mitch
Taylor's observations on the fate of the species, cited in
a recent issue of The Outdoor Edge (British Columbia). Taylor writes: "No
evidence exists that suggests that both [polar] bears and the systems
that regulate them will not adapt and respond to the new conditions.
Polar bears have persisted through many similar climate changes."
Taylor notes that there are 20 significant populations of polar
bears around the top of the globe. Of the 13 in Canada, 11 are either
stable or increasing in size. The western Hudson Bay population
is under stress, but "the reason seems to be that the conditions
for the bears there in the mid-1980s were exceptionally good." This
population peaked two decades ago, and "their current decline
is neither precipitous nor unnatural."
In fact, the polar bear population in Canada has increased 25 percent
in the past decade. Worldwide, there are 22,000 to 25,000 polar
bears, whereas 50 years ago, there were only 8,000 to 10,000 — a
150 percent increase, according to Taylor.

Peat and repeat
I read with concern in "The

The Canadian peat industry has adopted a Preservation and Reclamation
Policy, which requires that a thick layer of peat be left on fields
when harvesting ceases. Our industry now restores or reclaims nearly
all the bogs that have been harvested.
The restoration techniques we use were developed through extensive
research by Université Laval and other universities and were
funded by the industry. To date, more than $3 million has been invested
in the research and, using the techniques developed, several hundred
hectares have been restored. You may recall that you published an
article in your July/Aug 2004 issue entitled "Our lady of
the bog" which describes this research. The investment made
by industry and the success of Line Rochefort's research have
made Canada a world leader in peatland restoration.

Quarry watchdog
Your Explorer article ("The
almighty Bruce,"Jan/Feb
2007) brought welcome attention to the Niagara Escarpment, which
is undoubtedly the most prominent and spectacular topographical
and ecological feature of southern Ontario. Those who treasure it
are grateful for the protections from most development provided
by the Niagara Escarpment Plan, which was the first large-scale,
environment-first, land-use plan to be approved in Canada, covering
almost 184,000 hectares. It is also fortunate that there is a forward-thinking
provincial agency, the Niagara Escarpment Commission, to implement
the plan and recommend new policies to better protect the escarpment.
At the same time, citizen vigilance is essential for development threats
are never-ending. Our organization, representing 30 province-wide
and community associations, has monitored development all along the
escarpment and advocated for stronger protection since our founding
in 1978. Arguably the biggest challenge is applications to establish
new stone quarries and expand existing ones. In December 2006, the
Ontario Cabinet denied our appeal and approved the expansion of an
escarpment quarry that was already the largest in Canada, right in
the middle of the Golden Horseshoe Greenbelt that the Province had
established in 2005, and several other quarry proposals are in the
starting gate. Watchdog groups like ours have our work cut out for
us.

A plague of us
Thanks for the excellent article on the pine beetle ("Pine
plague," Jan/Feb 2007). Some will tell you that the beetle
plague is a problem, but it isn't. It's a symptom. Some
will tell you that the beetle plague is a symptom and that the real
problem is global warming, but it isn't. Global warming is
a symptom too.
The real underlying problem is another plague: us, six billion
of us insanely striving for growth in a finite space. Six billion
of us living some real-life sci-fi horror, enslaved so deeply by
our hydrocarbon-guzzling machines that our bodies are becoming obsolete.
Think this is far-fetched? If we were any other creature, the
problem of our plague proportions would have been making daily front-page
headlines long before we got to this point.
Yesterday, it was Hurricane Katrina. This year, it is the pine beetle.
Next year, it will be something else, perhaps far worse. This is what
we can look forward to from now on if we refuse to deal effectively
with the twin disasters of our multitudes and our unbridled sense
of entitlement to material wealth and ease of mobility.

Teacher's delight
Thank you so much for your wonderful magazine. I am a grade four
teacher in Airdrie, Alta., and the article on the archaeological
dig in the Cypress Hills ("Eight
thousand years down," Nov/Dec
2006) was fantastic to share with my students.
The new Alberta Social Studies curriculum includes First Nations
history and culture as well as the history of our province and it's
people. The article enabled me to show the children that "history" is
being found even today and that perhaps one day, they too, will
walk in the footsteps of Gerry Oetelaar.
It also is giving the students a better awareness of what we drop
or throw away and put into our landfill sites. One day, our castoffs
may be found by others.
Please give my thanks and regards to all those on your staff who
continue to assist the teachers of this country as well as enlighten
and encourage the children of tomorrow to continue searching for
all the wealth this country has to offer, past and present.

Built to last
In the "Discovery" story on disappearing communities
("As towns go by," Jan/Feb 2007), sociologist Debra
Davidson says rural communities that survive beyond three generations
may be the exception rather than the norm. Well, I thought I would
let you know that our family has lived in Poltimore, Que., for seven
generations on my mother's side and six on my father's
side. Today, we still have four generations in town: me, my daughter,
my granddaughter and my great-grandson. We all live within a mile
of one another. My great-grandparents, grandparents and parents
are all buried here. Also, the post office is run by a family that
has been here for seven generations and the general store by a family
that's been here for four.

Camp Tot'em
The article on the Bruce Peninsula ("The
almighty Bruce," Jan/Feb
2007) brought back many fond memories. I prowled the area of The Grotto
in the late 1950s and early 1960s before the crowds arrived. Much
of hte nearby area, including Cyprus Lake, was undeveloped thanks
to a dentist from Detroit who owned it. He had a few buildings on
a small lake that was separated by Georgian Bay by a ridge of broken
stones. It was called Camp Tot'em because all your supplies
had to be carried in on your back. There was no road.
For your readers unfamiliar with The Grotto, page 36 shows an interior
view. That underwater blue area is an opening through the cliff.
Many times I dove into the pool and swam through this opening to
emerge in Georgian Bay.

Logged vs unlogged
Rachel Carson has written that "those who dwell among the beauties
and mysteries of the earth are never alone or weary of life." A
few years ago, I experienced the vacation that dreams are made of
as I circumnavigated the Queen Charlotte Islands. Words such as awe-inspiring
and breathless do not do justice to the scenes of majestic cedars,
bountiful salmon, incredible marine ecosystems and magnificent world
heritage sights of Haida culture that I was fortunate enough to experience.
Your article ("Keepers
of the forest," March/April
2007) brought back many fond memories and reminded me of the stark
contrast betweeen a heavily logged area of Graham Island and the
pristine unlogged forests of Moresby Island that we were able to
observe from the sea. It is most encouraging to see that the Watchmen
of Gwaii Haanas have additional keepers to help them substain their
Haida culture. Hopefully, the Haida carvers will be able to continue
to be able show the world their creative mastery on the cedar.

Vehicle dumps
I flew along the DEW Line sites from 1960, 1961, 1962 and 1963
so I found your story about the cleanup very interesting ("Undoing
the DEW Line," March/April 2007). But nothing was mentioned
about cleaning the waters around the sites, where hundreds to thousands
of vehicles were dumped. They would be parked on the ice just before
spring breakup, and down they would go. Some of these vehicles were
old, but an awful lot of them were brand-spanking new and were dumped
with gas in their tanks and their tires still on. They were discarded,
I believe, so that the United States Air Force could maintain its
money allotments.
George Gill

My father, Graeme (Tiny) Gagnon, worked as a heavy equipment mechanic
on the Dew Line in 1957 and I believe part of 1958. I was very young,
but the memory of him returning home after being away for months
at a time is engrained in my memory to this day. I also remember
hearing my mother cry in her bedroom at night when he had to go
back.
Dad was an avid amateur photographer and he sent home hundreds
of pictures taken in and around Seglak Bay and Frobisher Bay, some
of which I still have. Many are landscapes, but he also captured
the workers, the Inuit, the buildings, machinery and some of the
friends he made while working on the project. He was particularly
fond of the Inuit who named him (Kol-e-ic-tuk) which meant Tractor
Man. That is the phonetic spelling, as I have no idea how it is
spelled.
My Dad loved the North and he would be pleased that it is being
returned to its original pristine state.
Lorna (Gagnon) MacRury
Port Hawkesbury, N.S
It was with overwhelming nostalgia that I read "Undoing
the DEW Line" in your March/April issue. Having spent the last
half of the 1960s on various DEW sites in the Western Arctic (including
Jenny Lind Island), I am only too familiar with the reckless abandon
with which materials of all kinds were abandoned. All I can say
in our defense is that, back in those days, nobody cared — witness
the Sidney tar ponds, for example. There was another aspect to DEW
Line landfill policy which was conspicuous by its absence from Mr.
Johnson's story — that of driving heavy equipment which
was no longer economically maintainable a mile or two out on the
sea ice and simply waiting for spring thaw to dispose of it. Like
it or not, much of the Arctic Ocean sea bottom along the Alaskan
and Canadian coastline is a giant parking lot.
The DEW Line most assuredly did not become obsolete "almost
as soon as it was completed." For decades, Soviet doctrine
was that a missile strike would be accompanied by a wave of manned
bombers which would arrive over North America minutes after the
missiles had struck. The DEW Line made that unlikely, in the sense
that even if missiles were to strike, it would be at least another
hour before the really bad news arrived. By then — so the
logic went — B52s would be on their way to Moscow and within
hours, the only thing living on the planet would be cockroaches.
From this came the concept of MAD — Mutual Assured Destruction.
Must have worked, because we're still here.
The DEW Line continued to detect and report Soviet bombers which constantly
probed its effectiveness well in the 1980s. The DEW Line never played
a role — nor was it intended to — in ballistic missile
detection. However, BMEWS — the Ballistic Missile Early Warning
System — at Thule, Greenland, relied on the DEW Line for many
years as its primary communications link to the south.

From February 1955 to October 1957 I was employed by the Foundation
Company of Canada, the builders of the DEW Line, from Site 25 to
Site 42. I started as Senior Resident Engineer and ended as Project
Manager. From January 1986 until my retirement in 1993 I was employed
by Monenco Eyretechics (MEG), which provided project management
support services to the Department of National Defence for the construction
of the entire North Warning System. I am, therefore, keenly interested
in anything written about both projects.
I remember Bryan Pearson, who was quoted in the article, both from
his days employed by our catering contractor and in subsequent years
during my time with the North Warning Sytstem. The only point I
would challenge would be the statement that mechanics earned $3,000
a month. Not in their wildest dreams. The highest wages among the
hourly rated personnel was during 1955. Even then, they weren't
that high.
As for the sport of rolling drums down hills, this is the first
time I have heard that one and I have my doubts. We had a hard-working
bunch of people who had little time or energy for sport, let alone
playing with barrels.
There is no question we made a mess. The evidence is there. The
accumulation of drums is a story in itself. But what was the choice?
The air carriers wanted no part of transporting un-purged barrels
and, even if they did, we had neither the time nor resources to
re-handle them. If you consider what we accomplished on that project
and the time frame involved, perhaps the consequences will be better
understood.

Port pollution
The Discovery story on the new shipping terminal at Prince Rupert,
B.C., may be good news for the economy of the city, but it is bad
news for the environment. The $160-million project described in
the article is expected to alleviate congestion in other West Coast
ports, such as Los Angeles. But according to Bluewater Network (an
affiliate to the environmental group Friends of the Earth) which
analyses the effects that the shipping industry has on the environment,
the pollution generated in the Ports of Los Angeles/Long Beach every
day by container ships — 16 on average — produce as
many smog-forming emissions as one million cars. A single cruise
ship generates the emissions of more than 12,400 cars. These ship
smokestacks release toxic emissions that lead to acid rain, global
climate change, and damaging health effects to communities situated
near ports.

Still circling
What Madelaine Drohan failed to mention in her story about traffic
circules ("Going in circles," March/April 2007) is the
fundamental reason why they work so well in the United Kingdom and
don't work in North America.
In the UK, they drive on the left and the vehicle on the right
has the right of way. Thus, when entering a street, the car on your
right will be the car to hit you first if you don't take care.
Here, we drive on the right, but the car on the right still has
the right of way. When you enter a street, the car that hits you
won't even be the one you are looking for because the one
that the law says you have to give way to is the one on the right,
across the street.
When this is applied to traffic circles, it means in the UK, where
you are driving on the left, you turn left into the traffic circle
and the cars in the traffic circle automatically have the right
of way because they are coming from your right. Here, you turn right
into a traffic circle and you have the legal right of way because
the cars in the circle are coming from your left. The simple fact
is that no amount a signage is going to correct that fundamental
error. I suspect the number of signs they have to put up is the
reason your writer was told that traffic circles are more expensive.
The other reason, that traffic circles take more space, is a bare-faced
lie. Many traffic circles in the U.K. consist of nothing more than
a single traffic circle sign for each road entering the traffic
circle and a bronze circular plate somewhere between 25 and 30 centimetres
in diameter in the centre of the intersection. The intersection
itself is no bigger than most downtown Toronto intersections.
Richard Dinning
Mississauga, Ont.
I read James Raffan's piece on touring the northwest passage
aboard the Louis ("Polar
police," Jan/Feb 2007)
with great interest and a real sense of ... Been there, done that.
I did my MASc at the University of Waterloo between engineering and
environmental studies. The area of study was radar image processing,
to remove noise and measure texture. Sea ice mapping was one
of the applications. As part of this work, I was given the opportunity
to spend two weeks aboard the CCGS Louis S. St. Laurent in
the early part of 1988. There was a team heading out to sea-trial
a passive microwave radiometer to give the captain another tool to
use when visual navigation was impossible.
That field work was the highlight of my grad studies and the most
memorable work that I did in my whole university career. Everything
from the 2 am phone call telling us to get out to the Gaspé because
the ship would be briefly in port, through slinging our gear out via
helicopter, to mounting the radiometer (my Swiss army knife was critical — MacGyver
would have been proud), to the ice recon runs, to the biting wind
on the flying bridge, to the meals and good company was a fantastic
adventure. My "tour" was around PEI and Cape Breton
but there is much in the piece that was so very familiar regarding
the ship itself and the fine people who crew her.
Thanks for bringing back the memories!

Thank you for the article on Elk Island National Park ("The
enchanted forest," Sept/Oct 2006). During the 1980s, my children
and I cross-country skied through the park's many trails.
And yes, we skied alongside the bison. They seemed uninterested
in humans.
We lived, at the time, in the small town of Lamont, which is about
three kilometers from the park. There was no charge to use the ski
trails. Many happy memories remain of our days in the park.
