About this map

Chesterfield Reservoir dominates the landscape of this Caribou County region, serving as a primary water management feature fed by the Portneuf River. The map highlights the sophisticated irrigation infrastructure of the early 21st century, including the Toponce and Chesterfield Land Co Ditch and the Portneuf Dam at the reservoir's southern tip. This area is characterized by a network of drainage systems and canyons, with Jim Corneilson Canyon and Pole Canyon cutting through the terrain.

Water sources are vital to this high-country environment, evidenced by named features like Hibner Spring, Cold Spring, and Corduroy Spring. Smaller impoundments like Twentyfour Mile Reservoir and its associated Twentyfour Mile Dam further illustrate the controlled water usage in the area. Remote outposts such as Horse Camp and local thoroughfares like East Side Rd provide a sense of the rural connectivity and land use patterns of the period.
