Background
Ollalie Butte is a basaltic-andesite shield volcano that is older than about 25,000 years before present. North Pinhead cinder cone to the north is even younger, but its flows are glaciated, suggesting an age of >11,000 years (Sherrod, in Wood and Kienle 1990). Sisi Butte, another shield volcano and other cinder cones are located nearby.---
