About this map

Olallie Butte dominates this high-altitude landscape on the boundary of the Warm Springs Indian Reservation, where the borders of Clackamas, Jefferson, and Marion counties converge. This 1980s survey reflects a geography defined by historical surveying efforts and recreational infrastructure, notably documenting several early boundary surveys including the McQuinn Line-1887, Trueman Line-1882, and Campbell Line-1909. These lines trace the evolving demarcation of tribal and federal lands through the Cascades.

Dense concentrations of alpine lakes like Fish Lake, Lower Lake, and Si Lake dot the terrain, many supporting campsites such as the Paul Dennis Campground and Peninsula Campground. The presence of the Pacific Crest National Scenic Trail and the Indian Reservation Boundary Trail highlights the importance of this area for transit and conservation within the Mount Hood National Forest and Mount Jefferson Wilderness.
