The crater rim of Lava Butte scoria cone on the NW flank provides a view of the broad Newberry shield volcano. Many other NW flank cones and associated lava flows erupted about the same time as the Lava Butte cone and lava flow. Over the past 7,700 years Newberry has erupted both mafic and silicic lavas from flank vents and within the caldera, respectively.
