The two species of hare that inhabit the AT are the snowshoe hare and the brown or European hare.
The snowshoe hare change color with the seasons, dark brown in summer, white in winter, and a mottled brown with white for the white snow patches on the ground in the fall. They live from northern New Jersey to Maine. Hikers mostly see them during high population times, which only come around once every nine to ten years.
Larger than the snowshoe and consistently the same color throughout the seasons, the brown or European hare live in northern Pennsylvania, eastern New York and western New England up to Vermont.
It might not be winter where you are but it's winter at Maine's Baxter State Park, home to Mt. Katahdin, where two ill-equipped men went for a foolish hike.
