The crater rim of Lava Butte cinder cone on the NW flank provides a perspective of the broad Newberry shield volcano. Many other NW flank cinder cones and associated lava flows were erupted about the same time as the Lava Butte cone and flow, a little over 6000 years ago. Newberry has erupted both basaltic-andesite lavas from flank vents and rhyolitic lavas from within the caldera.
