Olallie Butte, Steep shield volcano in Marion County, Oregon

Olallie Butte is a steep-sided shield volcano of basaltic andesite in the Cascade Range, its summit at 7,219 feet. It is the highest point in the 50 miles between Mount Hood and Mount Jefferson, and glacial erosion has cut its northeastern flank and exposed the central volcanic plug.

A fire lookout tower was built on the summit in 1915 and remained in use until 1967. This tower was part of the region's fire monitoring system during the peak years of forest protection.

The name Olallie comes from the Chinook Jargon word for berries. The butte lies within the Warm Springs Indian Reservation, and huckleberry plants around nearby Olallie Lake typically ripen by the end of August.

The area is best visited from June to October when hiking conditions are favorable. The Pacific Crest Trail runs along the western side and offers several access points for visitors.

Olallie Butte's summit held a Forest Service fire lookout tower from 1915 until it was abandoned in 1967, and a cupola cabin stood there from 1920 until its roof collapsed in 1982. The butte lies within the Warm Springs Indian Reservation, and the Pacific Crest Trail crosses its western side.
