About this map

The Chitina River basin is the central focus of this 1951 survey, where the massive braided river channel dominates the topography as it flows westward. Along the northern bank, the Old Railroad Grade traces a path through the valley, marking the legacy of industrial infrastructure in this subarctic landscape. Near the settlement of Chokosna, the terrain transitions from the low-lying river flats to the prominent heights of Gilahina Butte and Lost Butte.

South of the main river, the elevation rises sharply toward Nelson Mtn, where numerous unnamed tributaries feed into Grant Creek and the Hanagita River. The northern portion of the quadrangle is defined by a series of distinct water bodies, including Chokosna Lake, Lana Lake, and Billy Lake, which sit between the Kuskulana River and the Chokosna River. This map captures a specific moment when surveyed land lines remained largely unmarked and the region's movement relied on the historic rail corridor and river valleys.
