USGS Topo · Published 2024About this map
Tongass National Forest dominates this coastal landscape along the southeastern Alaskan panhandle, where high alpine summits meet the intricate shorelines of Thomas Bay. The terrain is defined by a series of prominent elevations, including Jefferson Peak, Rodman Peak, and Pierce Peak, which overlook remote glacial lakes such as De Boer Lake and Spurt Point Lake. Navigation and access in this wilderness are marked by coastal landforms like Point Vandeput and Spurt Point, while the Spurt Lake Trl offers a rare terrestrial route through the dense forest and complex topography. The presence of Ruth Island and the sheltered waters of Porter Cove illustrate the maritime character of this region, serving as a contemporary record of its untouched natural features and surveying boundaries.
