About this map

The Susitna River dominates this mid-century Alaskan landscape, its braided channels creating the sprawling Delta Islands and a complex network of sloughs. Development follows the corridor of the Alaska Railroad, which serves as the primary spine for settlements like Caswell, Kashwitna, and Willow. This era shows a frontier transitioning toward organized transportation, evidenced by the Willow Station Landing Strip and various Tractor Trails cutting through the swampy lowlands.

Away from the rail line, the terrain rises toward the Kashwitna Knobs and is dotted with isolated Cabins and remote water bodies such as Trapper Lake and Neil Lake. The map details the hydrology of the Susitna Valley, tracing the paths of Kashwitna River, Willow Creek, and Little Willow Creek as they drain into the main river system. These features illustrate the early infrastructure of the Matanuska-Susitna region during a period of territorial survey.
