About this map

The confluence of the Salmon River and the Pahsimeroi River anchors this high-desert landscape in central Idaho, where the small settlement of Ellis serves as a primary waypoint. The map details a river-centric geography where water management and conservation are evident through the Fish Hatchery and a dedicated Gaging Station Gage 4635 near the river junction. The boundary between Lemhi and Custer counties runs through the northern reaches of the quadrangle, crossing through the deep incisions of Cronks Canyon.

Land use in the late 1980s is reflected in the network of 4wd tracks that penetrate the slopes of the Pahsimeroi Mountains, leading toward landmarks like Eagle Rock and a remote Prospect site. Several gulches, including Deer Gulch and Dry Gulch, feed into the valley, illustrating the drainage patterns that define this arid terrain. For the traveler or historian, the presence of the Roadside Park at the river's bend suggests the intersection of recreation and utility in this mountain corridor.
