About this map

Revillagigedo Island presents a complex interior of high peaks and interconnected waterways in this mid-century topographic record. The landscape is dominated by the massive profile of Mt Reid and a series of elongated freshwater basins, including the extensive Lake Grace and Manzanita Lake. These features reflect the glacial carving typical of Southeast Alaska, where deep fjords like Behm Canal and Carroll Inlet nearly isolate the island from the mainland.

Evidence of early human infrastructure and wilderness management is sparse but significant, marked by a Shelter Cabin and a Gaging Sta near the lake systems. The map traces the drainage patterns of Manzanita Creek and Calamity Creek, illustrating how the island's high-elevation snowmelt feeds into remote bodies like Swan Lake and January Lake. This 1955 survey data provides a baseline for the region before modern land-use changes, preserving the original nomenclature for these vital water sources and landmarks.
