Little Tonzona River flows through the heart of this Alaskan landscape, where the administrative boundaries of the Denali Borough, Matanuska-Susitna Borough, and the Yukon-Koyukuk Census Area converge. The terrain is defined by the complex drainage systems of the East Fork Little Tonzona River and Pingston Creek, showing the natural hydrology before any significant modern development. The map reveals a wild geography at the edge of three major Alaskan jurisdictions, highlighting the headwaters of the Big Salmon Fork and the intricate contours of the surrounding valleys. This 2017 survey serves as a precise record of the river channels and boundary lines in a region where the natural environment dictates the limits of human governance.
