About this map

Aspen Ridge dominates the northwestern corner of this landscape, where the high-elevation terrain gives way to an intricate network of waterways and irrigation infrastructure. The area is defined by its water management, featuring named ditches like Last Chance Ditch, Lindback Ditch, and Hope Ditch that redirect the flow from natural drainages such as Killpecker Cr and North Cottonwood Cr. This reliance on water diversion highlights the agricultural necessity of moving water across the Sublette County landscape to sustain local ranching operations.

Several reservoirs, including Elaines Detention Reservoir and Jewett Red Flat Reservoir, serve as key collection points in this arid region. Near the center of the sheet, Onion Springs emerges along Onion Creek, providing a namesake landmark for this stretch of Wyoming. Transportation is limited to a handful of routes like Ryegrass Rd and County Road 117, which thread through the draws and across the creeks.
