Olallie Butte is located on the border of Jefferson County and Marion County in northern Oregon. It is a shield volcano with steep sides. Olallie Butte is part of the Cascade Mountain Range. A fire lookout tower was built in 1920. The lokout was later abandoned in 1967. A 4 mile long trail goes to the summit.
