2021 Map of Sumdum D-5 SE

USGS Topo · Published 2021

About this map

Mt Sumdum rises prominently within the Tongass National Forest, marking a landscape defined by dramatic glacial activity and complex administrative boundaries. This 2021 survey illustrates the glacial extent of the Sumdum Glacier and the drainage patterns of Powers Cr, located at the intersection of the Hoonah-Angoon Census Area and Petersburg Borough. The topography here is dictated by high-altitude ice fields and deep-cut creeks, showcasing the transitional zone between these two major Southeast Alaska jurisdictions. The lack of modern road infrastructure emphasizes the isolation of this corner of the state, where transit is governed by the natural contours of the glacier and the steep relief of the surrounding peaks.
