About this map

The Skwentna River serves as the central drainage for this section of the Matanuska-Susitna Borough, where it is joined by the Chickak River and fed by the Happy River from the north. The landscape is defined by the sharp transition between the glacial river valleys and the rising elevations toward the south, where Old Man Creek winds through steepening contours. In the northwest, Shirley Lake sits on a high bench above the river systems. This survey documents the complex braided watercourses of the Alaska interior, highlighting the dynamic nature of these glacial rivers before they merge into larger downstream networks.
