Alaska Peninsula

The southern side of the Alaska Peninsula is rugged and mountainous, created by the uplifting tectonic activity of the North Pacific Plate subsiding under a western section of the North American Plate; the northern side is generally flat and marshy, a result of millennia of erosion and general seismic stability.

[6][7] The climate can be compared to that of parts of Scotland, the Aleutian Islands, Iceland, and Tierra del Fuego.

The Alaska Peninsula is home to some of the largest populations of native and undisturbed wildlife in the United States.

Besides the famous McNeil River and Katmai Alaskan brown bear populations, large herds of caribou, moose, wolves, waterfowl, and willow ptarmigan inhabit the area.

Their offspring, or fry, overwinter in the deep and food-abundant depths of these lakes until their migration to the sea in one or two years.

[7] Additionally, there are large populations of sea mammals in the North Pacific Ocean between the Alaska Peninsula and Kamchatka.
