2017 Map of Tyonek C-6 NW

USGS Topo · Published 2017

About this map

Tordrillo Mountains dominate this high-altitude Alaskan landscape, where the elevation reaches into the thousands of feet across the glacial terrain. The Trimble Glacier occupies the eastern portion of the sheet, illustrating the slow movement of ice through the mountain passes in the Matanuska-Susitna Borough. This 2017 study by the U.S. Geological Survey provides a precise vertical record of the ice and peaks through dense contouring. The map is primarily an exploration of the natural physical geography, showing no roads or human settlements, which highlights the isolation of this portion of the interior. It serves as a modern baseline for researchers monitoring changes in glacial extent and alpine topography in the Tordrillo range.
