1981 Map of Dunn Basin

USGS Topo · Published 1981

About this map

The Fort Hall Indian Reservation occupies the western half of this landscape, where the boundary line divides the high country of Dunn Basin from the meandering river valleys to the east. At this point in the early 1980s, the terrain is defined by the hydrologic split between the Blackfoot River and the Portneuf River, which flow through a network of remote canyons and springs. Small-scale agricultural and utility markers like storage bins and a borrow pit near Morgan Bridge signify the sparse human footprint in this corner of Idaho. Transportation is limited to rugged tracks such as the Portneuf Presto Trail and Deadman Road, reflecting a geography that remained largely focused on livestock grazing and water access. The map captures the meeting of Bingham and Caribou counties amid a complex series of drainage systems including Sunday Creek and Beaver Creek.
