Most of this lies within the recreation area, but the last are in the wildlife refuge. == Description == Beaver Creek flows from its headwaters through thick forest of white spruce and paper birch forests and tundra on the high slopes of the White Mountains, where limestone peaks reach on the creek's north and east side. The creek has plentiful gravel bars, and willows grow on its banks. The lower portion of the creek follows very convoluted course through Yukon Flats, an area that contains thousands of lakes. Geographical features of these lowlands include sloughs and oxbow lakes. Beaver Creek is part of an active alluvial stream system in one of the most productive waterfowl breeding areas in North America and the most productive in Alaska.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Beaver Creek (Alaska)」の詳細全文を読む スポンサード リンク
