On May 18, 1980, the Mount St. Helens became the largest and most destructive volcanic eruption in U.S. history. By the end of its cycle of fire and fury, 57 people had died.

Dorr fumaroles 2375 m (7800 ft) elevation at the base of the Cockscomb, the rocky, rugged northeast ridge of Mount Baker dividing the Park and Rainbow Glaciers (also see the map on the ‘About MBVRC’ page). Mount Baker's summit North East If sulphuric acid-rich water accumulates as a pool below the sulphur rich Door Funmole Field (Image above) and it persist as a layer long enough to reach Whalelech Dam, it will attack the concrete. However, even if the acid load from the water basin feeding into Whalelech does not greatly increase, occasional light fish mortalities may result near the mouth of the creeks. Greater acid and mineral loads, resulting from further increases in volcanic activity or other possible causes, could be more harmful, especially to the fish. Continued monitoring of Whalelech watershed and collection of low and water quality is needed to detect rapidly any changes in conditions at Dorr Crater and to provide warning of possible greater impacts on Whalelech Lake from any future increases in Mount Baker activity. Of course, if there is a lahar that hits the Whalelech system, it will cause a tsunami that will overtop the dams and spillways, smash everything apart all the way down in about two minutes. The same as the tsunami on Spirit Lake at Mount St. Helen's. |
