This week’s video may be heartbreaking for some, watching caribou stranded on ice floes on the Porcupine River in Old Crow, Yukon.

But don’t worry. Though not in the video, some did make it to shore.

Every year, the caribou migrate north and cross this river. Whether they windup stuck depends on when the ice breaks in relation to their migration.

"We've seen some run off the ice and we've seen another bunch of caribou jump off the ice and run up the bank," Dayna Lord, who shot the video, told the CBC. "A lot of people feel bad, but it's just something that happens every year."
