About this map

Nowitna River dominates the western half of this interior landscape, carving a complex series of tight meanders and abandoned oxbows through the low-lying terrain. The river's winding path indicates a dynamic hydrologic environment where the channel shift over time is clearly visible in the topographical contours. To the east, the elevation rises sharply into a series of ridges and upland basins drained by Mastodon Cr, which flows north toward the river valley. In the southeastern corner, the headwaters of American Cr emerge from the high ground. The lack of named settlements or infrastructure highlights the isolation of this portion of the Yukon-Koyukuk Census Area, where the topography is defined entirely by natural drainages and significant elevation changes between the river basin and the surrounding hills.
