Koyukuk Wilderness

Introduction

The United States Congress designated the Koyukuk Wilderness (map) in 1980 and it now has a total of 400,000 acres. All of this wilderness is located in Alaska and is managed by the Fish and Wildlife Service.

Description

Think of 3.5-million-acre Koyukuk National Wildlife Refuge, and water comes to mind: there are 14 rivers, hundreds of meandering creeks, more than 15,000 lakes, all forming the floodplain of the Koyukuk River. The lands of the refuge are still of great importance to the Alaskans who live in villages within or adjacent to its boundaries. Local subsistence activities include gathering meat, fish and berries, trapping of furbearers, and cutting house logs and firewood. There are no roads and no maintained trails, but the lower Koyukuk River provides a "highway" through the heart of the refuge.

Moose are common within the refuge. Brown and black bears wade into the rivers in night-less summer to escape swarms of mosquitoes and other biting insects. Lynx, coyotes, red foxes, wolves, and wolverines might also be seen. Beavers abound, and thousands of migratory waterfowl nest and raise their young within the productive river basin. The rivers and wetlands are also habitat to salmon, sheefish, pike and grayling.

Four-hundred thousand acres of the Koyukuk Refuge are preserved as Wilderness. Miles of boreal forest surround a unique geological feature -- the Nogahabara Sand Dunes. The roughly circular active dune field spans about 6 miles in diameter, and was formed thousands of years ago when wind-blown glacial sand was deposited at the base of the Nulato Hills. The isolated dunes are lightly vegetated, and continue to shift with the wind.

The Three-Day Slough area also lies within the Koyukuk Wilderness and receives some public use, primarily by moose-hunters in the fall. Fishing and hunting are allowed throughout the Refuge, subject to State and Federal regulations. Visitors should be respectful of private in-holdings within the Refuge, and hunters are asked to maintain the Native tradition of using all parts of the gifts from nature.

The Koyukuk Wilderness, like the rest of the Koyukuk Refuge, is very remote. When planning a trip, be prepared for minimal human contact outside of the villages, and consider that weather and other situations can create conditions that are life-threatening. Enjoy and respect the challenge, discovery and freedom of wildlands. Make demands on yourself, not on the environment, and leave little or no trace of your presence.
