About this map

Willow and Susitna anchor the northwestern and southwestern reaches of this survey, which documents the complex wetland and riverine landscape within the Matanuska-Susitna Borough. The mighty Susitna River cuts across the western edge of the quadrangle, serving as a primary geographical marker for this part of Alaska. Moving east, the terrain transitions into a dense network of marshes and water bodies, including Fish Creek and several lakes with names reflecting the region's indigenous heritage, such as Beq'estsiq' Tuyu'uh and T'leghes Bena Q'estsiq'.

Unlike many development-heavy maps, this 2023 edition highlights a landscape defined by its hydrology rather than its road networks. Researchers can trace the sprawling wetland systems that separate Cow Lake from the main river corridor, revealing how the water-saturated ground dictates the placement of settlements and seasonal transit routes. This record serves as an essential baseline for understanding the environmental and cultural geography of the Cook Inlet region.
