About this map

Patit (Site) marks a point of historical interest along the waters of Patit Creek within the northern reaches of the Umatilla N F. This 1967 survey, updated with 1981 data, reveals a high-country landscape of the Blue Mountains defined by deep drainages like Cougar Canyon and Gates Gulch. The elevation culminates at Cahill Mountain in the south, while the Thorn Lookout Tower provides a structural landmark on the high ridges.

A network of mountain access routes including the Kendall Skyline Road, Malcolm Grade, and Marll Road suggests a terrain utilized for forestry and recreation. The inclusion of Pioneer Memorial Park (W) and a Gravel Pit indicates localized land use patterns between the protected forest and the neighboring canyons. The map tracks the convergence of the North Patit Creek and West Patit Creek, illustrating the complex watershed that feeds the North Fork Touchet River further west.
