Trammeled tundra above Kusitrin Lake

Image of a tiny wood frog with a black eye stripe is dwarfed by the palm of the person's hand on which it sits.

A frog that lives in Kobuk Valley National Park spends the winter as an ice cube. In the fall, the Wood Frog burrows under leaves on the forest floor. Its temperature drops to 20° F or lower until spring, at which point it thaws out and goes on its way.
