Scientists from the U.S. Geological Survey take gas samples at Devils Kitchen near the Crater Rock lava dome on the upper SW flank of Mount Hood. The Crater Rock area produces vigorous gas emission and results in extensive hydrothermal alteration of rock masses over broad areas. Photo by Bill Chadwick, 1982 (U.S. Geological Survey).
