| Summary: | The author has identified the following significant results. Combined aerial IR surveys and DCP heat flux estimates at Mt. Baker, Washington, revealed that recurrent snow, ice, and debris avalanches were in part induced by subglacial geothermal emission and led to the prediction that geothermally-induced volcanic events would occur again at Mt. Baker. On March 10, 1975, the prediction was substantiated when significant and sudden increase in subglacial steam emission perforated the crater glacier in Sherman Crater at Mt. Baker. Analysis of sterographic pairs of LANDSAT MSS images led to the discovery of three large ring structures (the largest, 34 km in diameter) that were interpreted as volcanic centers and possible collapsed calderas or volcanotectonic depressions of post Miocene age in Lassen volcanic region.
