The Clarks Fork Yellowstone River dominates the western edge of this Carbon County landscape, where the small community of Edgar serves as a focal point for the surrounding agricultural district. The map reveals an intricate network of irrigation systems essential to the valley's economy, including the Prosperity-Granite Ditch, Edgar Canal, and Orchard Canal. These man-made waterways contrast sharply with the natural drainage of Fivemile Creek and Two Bear Creek, which flow toward the river from the higher elevations to the east.
