1959 Map of Yost

About this map

The Upper Raft River Valley serves as a geographic centerpiece for this 1959 field survey of the Utah-Idaho borderlands. Settled life centers around the small communities of Yost and Lynn, which are connected by a network of unimproved roads and jeep trails navigating the high-altitude terrain. The presence of the Junction School and the Yost Cemetery marks the social and ancestral centers for the ranching families who worked these isolated valleys before modern infrastructure arrived. To the south, the Raft River Mountains dominate the landscape, with landmarks like Mahogany Peaks and Marble Canyon Peak rising above the timberline.
