About this map

Shoshone River meanders across this mid-1960s landscape, serving as the lifeblood for an extensive network of irrigation infrastructure north of the Roan Wash badlands. The map reveals a complex water management system designed to transform the high desert of Powell Flats, featuring the Willwood Canal, Elk Lovell Canal, and the Willwood Aqueduct. This irrigation network supports a grid of agricultural development defined by numbered roads and lanes, such as Road Eight and Lane Ten.

Evidence of the region's historic transportation routes is preserved in the Jim Bridger Trail, which cuts across the drainage basins of Grass Creek and the North Branch Whistle Creek. The topography shifts dramatically from the leveled agricultural fields in the north to the dissected terrain of Peerless Coulee and Willwood Draw in the south, where various Gravel Pits indicate local resource extraction.
