In November of 1990, Newberry National Volcanic Monument was created within the boundaries of Deschutes National Forest. Managed by the U.S. Forest Service, this monument provides a unique opportunity to view the Lava Lands of central Oregon. Newberry National Volcanic National Monument includes 54,000+ acres of lakes, lava flows, and spectacular geologic features in central Oregon. The highest point within the Monument is the summit Paulina Peak (7,985 ft.), showcasing views of the Cascades, Newberry Caldera and across the High Desert.

 Although commonly referred to as Newberry Crater, the "crater" is in fact a caldera formed when the overlying rocks collapse when a magma chamber is emptied. The caldera stretches across 17 square miles in the heart of the volcano. The 1,200 square mile volcano (about the size of Rhode Island) remains very active to this day. Newberry is both seismically and geothermally active. Geologists believe the caldera sits over a shallow magma body only 2 to 5 kilometers deep. Visitors see numerous cinder cones and vents (over 400 throughout the area), miles of basalt flows, as well as rhyolite flows of obsidian.
