| 説明 | The Delta Wild and Scenic River Watershed originates south of the Denali Highway and includes all of the Upper and Lower Tangle Lakes, the Tangle River, and the Delta River. The Delta River drains north through the Alaska Range, eventually joining the Tanana River and emptying into the Yukon River. The watershed includes 150,000 acres of land, 160 miles of streams and 21 lakes, providing excellent habitat for over 100 species of migrating birds and waterfowl as well as grayling, whitefish, lake trout, burbot, and longnose suckers. Much of the watershed is surrounded by arctic tundra with grasses and sedges makitg it a popular place for berry picking and for migrating caribou. Recreationists who visit during the fall, winter and spring will often witness subsistence hunting and gathering activities. The southern stretches of the Delta Wild and Scenic River Corridor are located within the Tangle Lakes Archaeological District and contain hundreds of archaeological sites listed on the National Register of Historic Places. Use of the area for hunting, mining, and subsisting are evidenced for the last 10,000 years.Learn more: www.blm.gov/ak/st/en/fo/gdo/delta_wild_and_scenic.htmlPhotos by Bob Wick, BLM |
