A band of caribou from Alaska's Teshekpuk Lake herd migrates across the vast coastal plain, traveling from calving grounds to windier areas where mosquitoes and bot flies are less likely to swarm. Protecting calving grounds, migration routes, and insect-relief areas is critical to the herd's health and survival.Photo:Subhankar Banerjee

These are tracks on coal seams made by the Western Arctic caribou herd over a very long period, perhaps many centuries or even millenia. The tracks are deeply etched in the coal surface. Caribou use this area both for calving and post calving aggregation. (Coal and the Caribou series)

The Teshekpuk Lake Caribou Herd rests in the Pik Dunes, a unique expanse of desertlike sand south of their calving grounds. The dunes offer the caribou relief from insects, their most numerous and relentless "predators." After calving takes place, insect-relief areas become essential for caribou survival.
