2017 Map of Tyonek C-8 NW

About this map

The Alaska Range dominates this landscape in the Matanuska-Susitna Borough, where steep topographic contours reveal the high elevations and drainage patterns of the northern wilderness. The broad valley of the Skwentna River cuts through the southeastern corner of the quadrangle, serving as a primary hydrological artery for the surrounding peaks. This 2017 survey details a remote area defined by glacial and snowmelt-fed tributaries, including the sharp descent of Crystal Cr and Emerald Cr. The land is divided into large sections of the Public Land Survey System, specifically Townships 18 and 19 North, covering Ranges 20 and 21 West. The absence of roads or permanent settlements on this sheet highlights the isolation of this portion of the range, preserved here in high-resolution detail for land management and geological study.
