The direction of the headwaters stream is northwest at first, then sharply northeast before April and Easter creeks enter from the right slightly north of the North Slope Borough boundary.〔 The river continues northeast for much of its course until it turns northwest again on the lower reaches after receiving the Okokmilaga River from the right.〔 Major tributaries of the Killik are April and Easter creeks, as well as the Okokmilaga.〔 North of Easter Creek, tributary streams, such as Aniakvik Creek and Nigaktukvik Creek, flow predominantly through short, narrow, V-shaped valleys. The main stem flows down a U-shaped glacial valley containing lakes, sand dunes, lateral moraines, and alpine tundra.〔"Trails">(【引用サイトリンク】url=http://www.trails.com/tcatalog_trail.aspx?trailid=CGA013-003 )〕 This valley, about wide initially, widens to between on the lower reaches, and the river becomes braided.〔 Copious stretches of dwarf birch (betula nana), and sedges, with large expanses of sedge bogs and tussocks dominate the tundra. The Killik is fed largely by precipitation and snow melt, and hence its waters are relatively clear of the sediment that characterizes glacial streams. ==See also== *List of rivers of 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「Killik River」の詳細全文を読む スポンサード リンク
