2021 Map of Sumdum B-4 NE

USGS Topo · Published 2021

About this map

Tongass National Forest dominates this Alaskan landscape, characterized by the winding path of the Chuck River. This high-elevation wilderness within the Petersburg Borough shows a complex network of glacial valleys and steep ridgelines, typical of the coastal rainforest interior. The mapping focuses on the intricate topography of the region, where the river system carves through heavily contoured terrain. Without the presence of developed roads or settlements, the map provides a clear picture of the undisturbed natural drainages and primary watercourses that define this part of the forest. Researchers can observe the interaction between the alpine elevations and the hydrologic patterns of the river basin as it was documented in this twenty-first-century survey.
