The Little Blackfoot River carves a significant path through this part of Powell County, shaping a landscape defined by the transition from the Avon Valley into the high country of the Boulder Mountains. Near the settlement of Avon, the topography is marked by numerous drainages such as Sixmile Creek and Homestead Gulch. This 2024 survey captures the modern infrastructure of the region, including the route of Old Hwy 10 and the various residential and access roads like Choke Cherry Ln and Shaman Dr that branch off toward the foothills.
