About this map

The Shoshone River winds through this section of Park County, carving a distinct valley between the irrigated agricultural lands of Powell Flats and the broken terrain of Roan Wash to the south. This mid-1960s landscape is defined by an intricate network of water management, including the Elk Lovell Canal, Willwood Canal, and various laterals that transformed the high desert into productive acreage. These engineering efforts are further evidenced by a prominent Aqueduct and numerous ditches following the local topography.

Historical transportation routes are well-represented, most notably by the Jim Bridger Trail, which cuts across the river valley. The map also documents a local Landing Strip and an orderly grid of rural roads, including Lane Eleven and Road Eight, which reflect the systematic settlement of the Big Horn Basin. Small-scale industrial activity is marked by Gravel Pits near the river, while the natural drainage of Peerless Coulee and Grass Creek shapes the southern portion of the quadrangle.
