The Lava Cascade lava flow, erupted from the NW rift zone about 6200 years ago, cascaded down the ramp that cuts across the center of the photo. The Lava Cascades flow was the longest flow on the upper NW rift and traveled about 8 km to the NW from its vent. The forested area at the extreme right is one of three large kipukas of older lavas that were surrounded by the flow. The flow in the foreground, called the Lava Cast Forest flow, originated from another fissure vent at about the same time. The NW rim of Newberry caldera rises in the distance.
