2021 Map of Bradfield Canal A-3 NE

USGS Topo · Published 2021

About this map

The Coast Mountains dominate this remote Alaskan landscape, where the high peaks and glaciers of the Tongass National Forest transition into deeply carved drainage systems. This 2021 digital survey by the U.S. Geological Survey maps a rugged interior wilderness where natural elevation and glacial hydrology dictate the terrain. The presence of Lake Cr winding through the steep valleys highlights the importance of freshwater runoff in this part of the Ketchikan Gateway Borough. Because this area lacks modern road infrastructure or permanent settlements, the map focuses on precise topographical data and the natural hydrography essential for navigating the Alaskan backcountry. Researchers can trace the complex network of mountain ridges and unnamed glacial features that define this high-latitude ecosystem.
