1963 Map of Rattlesnake Ridge

About this map

The Salmon River carves a deep canyon through this portion of Central Idaho, serving as the boundary between Nez Perce and Idaho Counties. The landscape is dominated by the steep, rising elevation of Rattlesnake Ridge, which is bisected by a network of drainage systems including Slick Ear Creek, Guthery Creek, and Cottonwood Creek. Human presence in this drainage basin is sparse, represented by remote outposts such as Flynn Creek Ranch and the historical Camp Thomas (Site). Access to these sites and the various springs, such as Thorn Spring, is limited to a narrow network of a Trail and a Jeep Trail, indicating the isolation of the cattle ranching or seasonal activity in the area during the early 1960s. The topography illustrates the significant vertical relief between the river floor and the high ridgelines.
