2023 Map of Talkeetna Mountains B-3 SE

About this map

The Talkeetna Mountains dominate this high-elevation landscape, where the headwaters of several major waterways originate. This 2023 survey by the U.S. Geological Survey details the complex drainage patterns of Kosina Creek and the Black River, providing a detailed look at the hydrology of the Matanuska-Susitna Borough. The terrain is defined by extreme relief and glacial valleys, with Aspen Creek carving through the western portion of the quadrangle. The lack of infrastructure or settlements on the map underscores the area's character as a primary wilderness frontier, where surveying efforts continue to refine our understanding of this remote Alaskan interior.
