The mighty Brooks Range marks a 1,126 kilometre long continental drainage divide in North America’s far northern reaches. Here, rivers running north empty into the Arctic Ocean, while those running south flow into the Yukon River. This remote massif is estimated to be 12.6 crore years old and contains a rich fossil record of the ancient seabed it once was. Found among the tundra and stands of spruce trees are fossilised corals from the Cambrian period. A portion of the eastern Brooks Range is within the Arctic National Wildlife Refuge. And wildlife is certainly abundant: Massive herds of caribou live here, including the 4,90,000-strong Western Arctic herd, as well as the Porcupine caribou, whose yearly 2,414 kilometre long trek along the range is considered the longest annual migration of any land mammal in the world.
