2024 Map of Dunn Basin

About this map

Morgan serves as a central reference point in this high-altitude landscape where the Blackfoot Mountains dominate the terrain. The area is defined by a complex drainage network, with the Blackfoot River winding through the eastern reaches while the Portneuf River carves its path further south. These waterways are fed by numerous seasonal and perennial streams including Beaver Creek, Supon Creek, and Deadman Creek. The namesake Dunn Basin sits as a high upland bowl, surrounded by ridgelines and traversed by local access ways like Trail Creek Rd and the Portneuf Presto Trail Rd. This 2024 survey documents the rugged cattle-and-timber country along the Bingham and Caribou county line, where the topography transitions from high peaks to the marshy edges of the Blackfoot Reservoir drainage basin.
