1990 Map of Sleepy Ridge

About this map

Haas Ridge and Sleepy Ridge dominate this corner of northeastern Oregon, defining a landscape of deep drainages and high divides within the Wallowa National Forest. Compiled from early 1980s aerial photography, the map documents a transition in land use, where former livestock sites like the Haas Horse Troughs (Site) persist alongside the designated Hells Canyon Wilderness. Waterways such as Lightning Creek, Medicine Creek, and the curiously named Windy Hell Canyon carve through the terrain, illustrating the complex hydrology of the Hells Canyon National Recreation Area. Higher elevations are marked by distinctive landmarks including Bald Knob, Grassy Knoll, and the high reaches of Summit Ridge. The map's detail provides a record of traditional resource access points and modern recreational boundaries as they stood at the start of the 1990s.
