2015 Map of Simpson Draw

About this map

Gillespie Reservoir anchors the southeastern landscape of this Converse County quadrangle, where the ephemeral drainage systems characteristic of the Wyoming high plains define the terrain. The network of waterways includes Simpson Draw and its tributary, the West Fork Simpson Draw, which carve through the undulating topography alongside W Fork Shawnee Cr. This 2015 survey illustrates a rural ranching environment structured by a grid of range and township lines, including t33n r69w and t34n r70w. Transportation across this expansive territory relies on gravel and dirt routes such as York Ranch Rd and Flat Top Rd, reflecting the sparse but enduring human footprint in the region. The map provides a detailed view of the natural water management through features like Sand Draw, essential for understanding the historical land use and hydrologic patterns of the American West.
