1961 Map of Sumdum A-3

About this map

The glacial landscape of the Tongass National Forest is defined here by the massive Baird Glacier, which dominates the northern reaches of this coastal Alaskan region. Flowing toward the waters of Thomas Bay, the terrain is carved by significant drainages including the Farragut River and Cascade Creek. This 1961 field-annotated survey, updated with 1970s hydrographic data, details the intricate shoreline where Ruth Island and Spray Island sit near the mouth of Scenery Cove. Peaks like Agassiz Peak and Dome Peak rise sharply from the water's edge, illustrating the dramatic elevation changes characteristic of the Cosmos Range. Interior lakes, such as Swan Lake and Scenery Lake, appear as isolated basins among the high ridges of Jenkins Peak and Fighting John Peak.
