1951 Map of Emigrant Gap NW

USGS Topo · Published 1958

About this map

Emigrant Gap Ridge dominates this Natrona County landscape, serving as a prominent topographic spine between the high plains and the drainage of South Fork Casper Creek. This mid-century survey, published as part of the Missouri River Basin development program, documents a complex network of water management features essential to the region's ranching and agricultural economy. The presence of the Casper Canal, several levees, and multiple segments of Casper Ditch (Aban'd) reveals the evolution of local irrigation and water rights. In the southern portion of the quadrangle, Hot Springs and Tudor Draw indicate natural water sources, while scattered windmills signify the ongoing effort to sustain livestock across the arid draws and gulches, including Clarks Gulch and Tie Bridge Gulch. Industrial history is noted by the inclusion of a Gravel Pit (Aban'd) and a regional Pipe Line cutting diagonally across the northern sections.
