2011 Map of Ashton

About this map

The Ashton and Marysville settlements serve as the focal points of this eastern Idaho landscape, where the confluence of the Henrys Fork and Fall River dictates the local geography. The territory is defined by an intricate network of irrigation infrastructure essential to the region's agricultural character, including the Farmers Own Canal, Marysville Canal, and the North Lateral Marysville Canal. These man-made waterways transition into a more dramatic natural topography to the north and east, marked by deep incisions like Box Canyon, Jump Off Canyon, and Hale Canyon. Significant local landmarks are grounded in the water economy, notably the Ashton Dam on the Henrys Fork and the Ashton Fish Hatchery to the southwest. The grid-like road system, featuring names like Marysville Rd and Fall River Rd, provides a clear view of how land was partitioned and settled around these vital water sources.
