Diamond Peak Wilderness and the Oregon Cascades Recreation Area dominate this high-altitude landscape in the Cascade Range, where multiple county lines and national forest boundaries converge. The topography is defined by prominent volcanic features like Emigrant Butte, Hills Peak, and Warm Spring Butte, with the Pacific Crest National Scenic Trail skirting the eastern edge near Summit Lake. Water drains through complex networks including Paddys Valley and the Middle Fork Willamette River, punctuated by numerous alpine basins such as Rockpile Lake, Marie Lake, and Hemlock Lake. The presence of several quarries and a pit in the northwest suggests limited resource extraction amidst the protected wilderness. This 1997 revision provides a precise view of the region's transition from managed timberlands in the Willamette National Forest to the strictly preserved wilderness areas of the high Cascades.
