About this map

Little Summit Prairie sits at the heart of this high-elevation landscape within the Ochoco National Forest. The 1966 data, revised in the mid-1980s, reveals a terrain defined by its water sources and ridges, including the prominent Paulina Butte LO and the southern Upper Pocket. Numerous named springs like Wilson Spring, Big Spring, and Roba Spring suggest the importance of water management for forest operations and livestock in this portion of Crook and Wheeler Counties.

A network of forest roads connects seasonal locations such as the Little Summit Campground and Big Spring Campground. The map tracks several reservoirs, including Morgan Reservoir, Corral Reservoir, and Ruby Reservoir, which underscore the human alteration of the drainage basins for Thornton Creek and Hewed Log Creek. Notable landmarks like Minifie Ridge and Roba Butte provide fixed points for navigation through the dense contours of the Ochoco range.
