About this map

Revillagigedo Island presents a complex landscape of deep fjords and interior alpine lakes in this late 1940s survey. The map centers on the glacial geography of the Thorne Arm and Carroll Inlet, where the shoreline is punctuated by landmarks such as Eve Pt and Elf Pt. Evidence of the region's industrial history is found at the Sealavel Mine (Aband) near Beaver Lake, indicating the early 20th-century push for mineral extraction within the Tongass National Forest.

The interior is defined by an intricate network of freshwater systems, including Ella Lake and the connected Gokachin Lakes. Elevations rise sharply to summits like Painted Peak and Notch Mtn, while the marine passages of Behm Canal and Narrow Pass serve as critical maritime corridors. A lone Gaging Sta on Gokachin Creek suggests the era's focus on monitoring the water resources of this maritime wilderness.
