2021 Map of Sumdum A-4 NW

USGS Topo · Published 2021

About this map

The Tongass National Forest dominates this Alaskan landscape, where the Coast Mountains meet the intricate tidal waters of the Holkham Bay area. This 2021 survey documents the dramatic verticality of the terrain, rising from the North Arm and South Arm to sharp summits. Distinctive topographical features like Jamestown Peak, Saranac Peak, and Alaska Peak overlook the deep fjord-like waters. Navigational points such as Francis Anchorage and the narrow Sanborn Canal provide critical orientation along the shoreline, while smaller maritime landmarks like Flock Rock and Bay Point Knoll mark the boundary between the sea and the high alpine slopes of Man-of-War Peak. The map illustrates a wilderness defined by steep contours and glacial carved inlets, largely untouched by infrastructure but rich in named natural features.
