1952 Map of Holy Cross D-1

About this map

The Innoko River winds through a complex network of wetlands and shifting channels in this mid-century Alaskan interior survey. The terrain is characterized by the expansive alluvial flats of the river valley, where the Holikachuk Slough branches away from the main current. This landscape reflects a period of aerial mapping conducted by the Army Map Service, relying on photogrammetric methods from 1951 to chart the difficult-to-access western reaches of the state. Surveyors established critical triangulation points such as VABM Chalet 1032 and ABM Innoko 630 to anchor the topography. The map also delineates the Kateel River Meridian boundary, marking the intersection of public land survey systems in a region defined more by its watercourses than by human infrastructure.
