About this map

Skwentna serves as the primary focal point in this remote Alaskan landscape, situated near the confluence where several glacial waterways meet. The map reveals an intricate network of braided river systems, dominated by the wide path of the Yentna River and the Kahiltna River. These waterways, along with smaller tributaries like Moose Creek, Middle Creek, and Fish Creek, define the movement and settlement patterns within the Matanuska-Susitna region. The terrain is a complex mosaic of wetlands and small ponds, characteristic of the low-lying basins in this part of the state.

Away from the primary river corridors, Lockwood Lake sits in the southeastern portion of the survey, surrounded by an expanse of marshland. The lack of established road networks highlights the reliance on river travel and bush aviation for access to this area. This map provides a clear view of the natural hydrology and township boundaries, including t21n r8w and t20n r7w, before the landscape shifts toward the higher elevations of the surrounding mountains.
