2023 Map of Talkeetna A-4 NW

About this map

The Nakochana River winds through the central portion of this remote Matanuska-Susitna landscape, demonstrating the complex drainage patterns of the Alaskan interior. This modern 2023 survey by the U.S. Geological Survey captures the hydrologic relationship between the Kichatna River and its northern tributaries before they reach larger valley systems. The elevation is defined by Nin Ridge, which runs through the center of the sheet, separating the southern river flats from the higher ground and smaller drainage systems like Gagnan Creek in the northeast. The lack of roads or established settlements on this sheet highlights the wilderness character of the Talkeetna region, where topographic details are primarily limited to natural watercourses and significant glacial-carved terrain features. Researchers can use this data to study current water flow and changes in the river morphology within the Matanuska-Susitna Borough.
