About this map

Dunn Basin and its surrounding watercourse network define this high-country landscape in eastern Idaho. The Blackfoot River flows through the central portion of the area, crossed by the Morgan Bridge near the small settlement of Morgan. The map reveals a complex web of drainage systems including Supon Creek, Deadman Creek, and the headwaters of the Portneuf River, which winds through the southwestern corner.

Remote transportation routes such as the Portneuf Presto Trail Rd and Lincoln Creek Rd illustrate the area's history of trail-based movement across the basin. In the southern reach, Austin Ranch is situated near the confluence of Grave Creek and Warbonnet Creek, representing the area's ranching heritage. Access into the reservation lands is noted via the Chesterfield Reservation Rd, emphasizing the region's intersection of tribal and agricultural boundaries.
