Here you'll find moose, foxes, beavers, martens, minks, wolves, wolverines, caribou, large populations of black and brown bears and millions of salmon. The Andreafsky River and its East Fork, in the northern section, flow along parallel paths southwest and drain into the Yukon River. Along both their Wilderness banks, in contrast to the relative flat treeless delta, grow forests of white spruce and balsam poplar. Near the headwaters the forests give way to alpine tundra.
Fishing is excellent and the bears know it.
Both rivers are scenic, but the East Fork has more trees and runs closer to the mountains. One hundred twenty-five miles of the Andreafsky and 137 miles of the East Fork are designated National Wild and Scenic Rivers, attracting river runners and anglers. Summers are cool with days of fog, gentle by Alaskan standards. Winters are cold and dry and severe. Airplanes, motorboats and snowmobiles are allowed in this trail-less Wilderness.
