Even for an experienced tundra traveler like photographer Kiliii Yüyan, the 13,238-square-mile Gates of the Arctic National Park & Preserve—which sits in the Alaskan interior, above the Arctic Circle—can be hard to picture.
“I think there’s this sense that the Arctic is a vast, barren plane,” says Yüyan. But the park, which protects parts of the 600-mile-long Brooks Range, is ridged with “incredibly photogenic and majestic” mountains unlike the coastal plains that make up most of the Arctic. “You’re in a true wilderness.”
