Three lava flows that erupted from fissure vents on the NW rift zone of Newberry volcano about 7,000 years ago can be seen in this photo. The Forest Road Flow in the foreground was one of the smallest. Behind it are the Lava Cast Forest and Lava Cascades flows. The latter traveled about 8 km from its vent. The northern rim of Newberry caldera forms the ridge on the horizon.
