These are the last words radioed by the 30-year-old volcanologist David A. Johnston, who was stationed on the nearby Coldwater Ridge. That ridge is now called Johnston Ridge and is the location of the Johnston Ridge Observatory. Moments after the transmission, the ridge was hit by the super hot pyroclastic flows from the lateral eruption of the mountain. This was the result of the collapse of the north side of the mountain. About one minute behind the hot gases and pulverized rock came the giant mud flows that swept up and over the ridge. Mr. Johnston's body was never found.
