Paulina Lake is the westernmost of two lakes within Newberry caldera and is seen here from Paulina Peak, the high point of the southern caldera rim. The lava flow entering the lake to the upper right erupted about 6,400 years ago from the Central Pumice Cone. The flow split into two lobes, and the other lobe traveled into East Lake, just out of view to the right. This was one of several eruptive vents within the caldera that were active during this eruptive phase.
