Leaving Gates of the Arctic National Park the river enters the Noatak National Preserve which exactly delineates the river's watershed. The ''entire watershed of the Noatak River,'' not just the river itself, lies within these two protected areas, from the headwaters to where it leaves the Noatak National Preserve, which is a point approximately 20 river miles upstream of Noatak village and 90 river miles upstream of the river's delta in Kotzebue Sound. Even on this last part of the river most of the watershed lies within either Noatak National Preserve or Cape Krusenstern National Monument, with only the immediate river valley outside of these protected areas.〔USGS 1:250,000 quads: Noatak, DeLong Mts., Baird Mountains, Ambler River, Misheguk Mountain, Howard Pass, Survey Pass〕 The Noatak basin is the largest undisturbed watershed in the United States.〔(【引用サイトリンク】url=http://www.nps.gov/noat/naturescience/index.htm )〕 The Noatak National Preserve alone encompasses .〔 There are small inholdings of private land within the National Preserve, some of these have private cabins. The only permanent settlement along the Noatak River is the village of Noatak. The village has a lighted public gravel airstrip, several small stores, post office, and a school.〔(Maniilaq Association Noatak website )〕 The Noatak is fed by a relatively large watershed: as for some other large braided Arctic rivercourses, rare severe rain events can result in temporary rapid inundation, to a depth of several feet, of normally dry river bars. There are a few small remnant glaciers in the Schwatka Mountains, their contribution to the water budget of the Noatak is negligible. ==Name origin== Named ''Inland River'' by surgeon John Simpson of the Royal Navy on a map he prepared in 1853, his wording appears to be a general translation of the Inuit name ''Nunulak'', according to the United States Geological Survey.〔 The name ''Nunatak'' could also mean "new land" or "belong to the land."〔 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「Noatak River」の詳細全文を読む スポンサード リンク
