James Kalluk spent much of his childhood inside an igloo in Canada’s far north, close to the Arctic Circle. Building that kind of home requires temperatures low enough to freeze the region’s countless lakes, a particular consistency of snow and a long-bladed knife the Inuit call a pana.
“Today, there’s not much snow and it’s harder to make an igloo,” said Kalluk, now in his early 70s. “You may find a spot here or there that’s good, but the snow is very difficult now. It’s different.”
