April 8, 2003: Karsten Heuer + Leanne Allison left the remote community of Old Crow,Yukon, to join the Porcupine Caribou Herd on their epic life journey. For 5 months the Canadians migrated on foot with the 123,000-member herd from wintering to calving grounds in Alaska's Arctic National Wildlife Refuge, and back again — 1500km across snow and tundra. They completed their journey on Sept. 8, 2003.
