The basaltic-to-dacitic Sprague River Valley volcanic field consists of small shield volcanoes, cinder cones, and about two dozen maars active from 5-1.5 million years ago (Sherrod, in Wood and Kienle, 1990). The youngest features are the Saddle Mountain basaltic andesite shield volcano and Taylor Butte, a basaltic cinder cone.
