It was created in 1978 to protect fish and wildlife breeding and support systems and preserve subsistence and recreational activities. Although the weather from late May to early October permits outdoor recreational activities, flying, boating and alpine activities are occasionally hampered or unsafe. Be prepared for delays in planned events and travel. All five species of Pacific salmon spawn here and freshwater fish are prolific, including whitefish critical to subsistence. There are moose, brown bear, caribou, black bear, beaver, muskrat, otter, fox, wolverine, mink, porcupine, ground squirrels, and marmots.
