2017 Map of Talkeetna A-4 NW

About this map

Nakockna River and the Kichatna River dominate this wilderness landscape in the Matanuska-Susitna region, where braided water channels snake through low-lying valley floors. The drainage pattern here reflects the dynamic nature of Alaskan glacial-fed rivers, which frequently shift course and reshape the surrounding wetlands. Rising between these major watercourses is Nin Ridge, a prominent terrain feature that provides a topographic contrast to the river plains. To the northeast, the smaller Gagnon Cr contributes its flow to the larger basin. This 2017 survey by the U.S. Geological Survey maps a region defined by its lack of permanent infrastructure, highlighting the raw physical geography of the Talkeetna area before any modern development or road networks reached this specific reach of the river system.
