Lake Superior

Isle Royale

A wilderness island in the middle of Lake Superior, home to the longest-running predator–prey study on Earth: wolves and moose, watched without pause since 1958.

Isle Royale

It's the least-visited national park in the lower forty-eight, and the reason is simple - you can only get there by boat or seaplane, it closes entirely for winter, and it's a long way out into the largest freshwater lake in the world. What's left is forty-five miles of roadless island: spruce and birch, inland lakes, a rocky shoreline, and loons calling across the water at night.

The moose swam over, more or less. The wolves came across an ice bridge in a hard winter decades ago. Penned together on one island with nowhere to go, they became the perfect natural experiment, and biologists have tracked both populations every single year since 1958 - the longest continuous study of its kind anywhere. The numbers rise and crash against each other: too many wolves, the moose thin out; too few moose, the wolves starve. A closed world, kept honest by hunger.

For a hiker it's just gloriously empty. You take a ferry out, shoulder a pack, and walk ridgelines with the lake on both sides, more likely to meet a moose than a person. Most people never make the trip. The ones who do tend to talk about it for years - the quiet, mostly, and the sense of being genuinely far from everything on an island the wolves had first.
