About this map

The Fort Lemhi Monument and Sacajawea Monument stand as central landmarks in this mid-century survey of the Lemhi Valley. The landscape is defined by the Lemhi River corridor, which serves as the primary axis for settlement and travel, connecting the small communities of Tendoy and Lemhi. This valley floor is hemmed in by the formidable Beaverhead Mountains to the east and the Salmon National Forest to the west, creating a corridor of high-altitude ranching and historical commemoration.

Local landmarks such as Ramsey Mountain and Hayden Basin reveal a rugged interior marked by numerous water sources, including First Basin Spring and Eckersell Spring. Small-scale resource extraction is noted by Prospects near Yearian Creek, while the presence of a Cemetery near the Fort Lemhi site reflects the deep roots of this pioneer and indigenous crossroads. The map also traces the route toward Lemhi Pass, a vital historical gateway across the Continental Divide.
