The Lemhi River valley serves as the central artery for this part of Lemhi County, Idaho, where the settlement of Baker sits along the foothills. The landscape is defined by the transition from the river bottomlands to the rising slopes of the Lemhi Range to the southwest and the high mountain drainages to the northeast. A network of ranch roads and historic alignments, such as Old Lemhi Rd and Old Highway 28, follows the natural contours of the valley, reflecting the area's long-standing reliance on the river corridor for travel and transport.
