2010 Map of Chesterfield

About this map

The settlement of Chesterfield and the neighboring agricultural valley are defined by a complex network of water management features in this 2010 survey. Irrigation is central to the landscape, evidenced by the Toponce and Chesterfield Land Co Ditch, Kelly Toponce Ditch, and the Downey Canal, which channel water from the Portneuf River and Toponce Creek to sustain local farms. The map documents the grid of rural roads such as Kelly Toponce Rd and Hansen Rd that connect outlying properties and the Chesterfield Cemetery to the historic townsite. Further south, the map tracks the path of Old Hwy 30 near the community of Kinport. This modern USGS study provides a detailed record of land use and water rights in Caribou County, showing how the landscape transition between the valley floor and more rugged terrain like Higginson Canyon has been adapted for ranching and settlement.
