Summary
Hawaii Volcanoes National Park. Portable drilling rig used at Kilauea Volcano in 1965-66. The drill (left) is powered by a connected chain saw motor (in left hand of operator) and is lowered and raised by a hydraulic feed (in the right hand of the operator). Coolant water is pumped (right center) from two fifty-gallon drums. Steam rises from the March 1965 vent area; the main vent is out of the picture toward the right background. The highest level of the lava lake before drainback is recorded by the "bathtub ring" in the background. Circa 1968. Figure 7, U.S. Geological Survey Professional paper 1004.
