Muskox reports concentrate hard on Alaska’s North Slope, the open coastal tundra north of the Brooks Range, with smaller clusters in Gates of the Arctic National Park and Preserve and the Arctic National Wildlife Refuge. That pattern traces the species’ real comeback story: muskoxen were wiped out in Alaska by the late 1800s, and every animal on the North Slope today descends from a Greenland herd released on Nunivak Island in the 1930s.
Out on the tundra, muskoxen stay put through the dark winter instead of migrating, pawing through snow with their heads and hooves to reach frozen sedges, grasses, and willow. When wolves or a bear close in, the herd doesn’t scatter. Adults form a tight ring facing outward with calves tucked behind them, a defense built for animals that chase down stragglers, not for a hunter with a rifle.
Records run heaviest from May through July, when the near-constant daylight of an Arctic summer gives observers their only real window onto the tundra. The herds are on the same ground come January; they’re just far harder to reach and see.
