About this map

Olallie Butte dominates the northeastern corner of this high-altitude landscape, marking a prominent boundary point between Marion, Wasco, and Jefferson counties. The area is characterized by a dense concentration of glacial lakes, including the large Olallie Lake and Monon Lake, alongside smaller water bodies like Nep-te-pa Lake and Mangriff Lake. This 1990s revision reveals a complex jurisdictional meeting point where the Mount Hood National Forest and Willamette National Forest intersect with the western edge of the Warm Springs Indian Reservation.

Resource extraction and recreation are noted through features like the Ruddy Hill Quarry and various boat ramps, set against the protected environment of the Mount Jefferson Wilderness. The map highlights the Olallie Lake Scenic Area, reflecting a landscape managed for both timber and preservation. Distinctive volcanic terrain is evident in the many peaks, such as Potato Butte, Pyramid Butte, and Twin Peaks, which define the drainage patterns of Squirrel Creek and the headwaters of the Clackamas River.
