1954 Map of Lake Clark C-6

About this map

The Mulchatna River and Chilikadrotna River dominate this interior Alaskan wilderness, revealing a landscape defined by an intricate network of glacial melt and alpine drainage. Mapped from aerial photographs taken between 1953 and 1957, the terrain is anchored by Marys Mountain, which rises between the river valleys. The hydrology of the region is exceptionally detailed, showing the convergence of Big Bonanza Creek and Bonanza Creek as they feed into the larger river systems. In the southern portion of the sheet, the Chilchitna River and Dummy Creek flow through unsurveyed lands, with locations predetermined by the Bureau of Land Management. This survey captures the remote character of the Seward Meridian before significant modern encroachment, preserving the original hydrographic patterns and landform names used by early 20th-century surveyors and field annotators.
