Ptarmigan Cr carves through the northern reaches of this landscape, a remote section of the Yukon-Koyukuk region characterized by significant elevation changes and deep drainage basins. The terrain is defined by the high divides between the watercourses of Jackson Cr and Mission Cr, illustrating the complex hydrological network of the Alaskan interior before these waters eventually join larger river systems. Surveyed for the t6n r21w and t5n r21w townships, the map provides a precise record of the natural topography in an area devoid of permanent settlements or road infrastructure. This 2016 survey is an essential resource for understanding the untouched wilderness and the natural flow of mountain streams in this specific corner of Alaska.
