Cascade Lakes Scenic Byway
Newberry National Monument, OR
Newberry is not part of the Cascade Mountain Range because it lies at the juncture of three major fault lines.
While there is a magma chamber far below the volcano's's caldera, the molten rock may not be produced by the melting oceanic plate.
Geologists do not fully understand where the magma comes from, but temperatures in excess of 500 degrees Fahrenheit 3,000 feet below the caldera floor indicate that the volcano is far from dead.
