About this map

The vast interior wetlands of Alaska are defined by a labyrinth of interconnected water bodies on this 1951 sheet, centered on the expansive Ewan Lake. This unroaded landscape, based on 1950 aerial photography and Bureau of Land Management data, reveals a complex hydrologic network where Middle Lake and Dog Creek traverse the muskeg and forest. Notable for its isolation, the map shows very little human infrastructure beyond scattered Cabins, indicating the area's primary role as a seasonal hunting or subsistence ground during the mid-twentieth century.

A significant feature of the terrain is the large Crosswind Lake, which is also identified by the alternative name Charley Lake. The map details smaller, distinctive basins such as Horseshoe Lake, Round Lake, and Birch Lake, which are characteristic of the pothole-studded topography of the Gulkana region. This survey provides a baseline for the natural shoreline configurations before later ecological or climate-driven changes altered these northern water systems.
