This weekend marks the 33nd anniversary of 1980 eruption of Mount Saint Helens that killed 57 people and forever altered the local environment. While Saint Helens might be the most famous volcano in the region-it's not the most dangerous. That distinction goes to Mount Rainer, which is actually one of the most dangerous volcanoes in the world. If it were to erupt, the heat would melt snow and ice that could create a mega mudslide that would wreak havoc through populated areas such as Seattle and Tacoma. The last time Rainer erupted was back in 1894.
