1951 Map of Pathfinder Reservoir NW

About this map

Pathfinder Reservoir dominates this high-altitude Wyoming landscape, where the waters of the North Platte River are impounded within a complex of granite peaks and wildlife sanctuaries. This 1951 survey, part of the Missouri River Basin development program, details the intersection of Natrona and Carbon counties along the reservoir's western reaches. The terrain is defined by dramatic elevation changes, notably Pathfinder Mountain and the jagged spine of Granite Ridge. The map documents the extensive Pathfinder National Wildlife Refuge, tracing the Wildlife Refuge Boundary across a network of points and inlets including Bishop Point and Woolf Point. Geodetic control is anchored by the VABM Pathfinder 6714 station, while drainage like Arkansas Creek feeds into the blue expanse of the high-desert basin.
