Young Creek
Young Creek is an east tributary of Nizina River in the U.S. state of Alaska. The stream, which serves as the main drainage on the north side of MacColl Ridge,〔(【引用サイトリンク】url=http://www.mindat.org/loc-203035.html )〕 flows through the Wrangell–St. Elias National Park and Preserve.
==Geography==
The stream is about long and heads in the mountain mass dominated by Pyramid Peak, from which Chititu Creek, Dan Creek, and Canyon Creek receive much of their waters. The water of Young Creek is derived in part from melting snow and glacier ice, and during the warm summer days is discolored with glacial silt. Young Creek occupies a typical glacial valley of broad U-shaped cross section. The upper part of the stream, formed by the union of two short forks, each a little more than long, flows over a flood plain between low brush-covered gravel benches. Below the big bend, where the stream turns to the west at a right angle to its upper course, Young Creek has intrenched itself in the valley floor and has cut a rather wide canyon that grows deeper and deeper downstream until, below Calamity Gulch, it attains a depth of about . From this point westward, the canyon becomes broader and shallower till the creek reaches the bars of Nizina River.
The Nizina gold field includes the drainage basins of three southeast tributaries of the upper Nizina River—Young Creek, Chititu Creek, and Dan Creek. Young Creek is the largest of the three streams, and its crescent-shaped basin surrounds that of Chititu Creek on the east, south, and west. Calamity Gulch and Gold Run are among the tributaries of Young Creek most frequently mentioned. These flow south from the ridge whose north slope is drained by branches of White Gulch, one of the forks of Chititu Creek.
