Crater Lake is one of several lakes in Oregon that reside inside volcanic calderas. The Newberry Volcano erupted some 75,000 years ago and subsequently collapsed, forming a five-mile diameter caldera. Newberry is much older than the 7,500-year-old Mount Mazama Caldera, containing Crater Lake. The Newberry Caldera is located 20-miles south of Bend, Oregon, and contains Paulina Lake and East Lake. Paulina Lake is the larger of the two, encompassing 1,530 acres and a depth of 250-feet. Like Crater Lake, Paulina and East Lake rely on snowmelt and rain, and Paulina Lake also has hot springs that feed it. Newberry remains active and its most recent eruption formed Big Obsidian Flow, a 1,300-year-old lava flow, the youngest in the state.
