2017 Map of Dunn Basin

About this map

Dunn Basin sits at the heart of this high-elevation landscape, where the waters of the Blackfoot River and the Portneuf River originate and diverge. This territory is defined by its complex drainage network, including Beaver Cr, Supon Cr, and Deadman Cr. The presence of the Portneuf Presto Trail Rd and Trail Creek Rd suggests a network of early transit routes through the mountain passes. Near the center of the sheet, Morgan Bridge serves as a critical crossing point of the river, while the boundary between Bingham Co and Caribou Co cuts across the southern portion of the quadrangle. The map reveals a remote ranching and transit landscape, where modern roads like Blackfoot Reservoir Rd follow the historical contours of the river valleys.
