Isle Royale is one of the most remote U.S. national parks. It stretches across one large island, its namesake, and more than 400 smaller ones in northwest Lake Superior. The park’s main draws are wilderness and wildlife, including beaver, otters, moose, martens and – for the moment – a very few wolves.

This fall the National Park Service has released four wolves captured from the mainland on Isle Royale. Once there were 50 wolves on the island, but inbreeding, climate change and disease all but wiped them out in the past decade. Meanwhile, moose – the wolves’ chief prey – are eating island greenery down to the nub, adversely affecting many other species.
