Mount St. Helens is an active volcano in Washington state. It lay basically dormant for over a century until the spring of 1980, when a series of earthquakes heralded a series of devastating eruptions that saw an avalanche of debris and hot magma, which sped away from the volcano at almost 500 kilometers per hour. Spokane was plunged into darkness during daylight hours. Ash fell 1500 kilometers away. Over fifty people died.

If virus outbreak guidelines allow, HRPO Education Program Specialist Amy Brouillette will give that facility's first talk on Mount St. Helens, to coincide with the thirtieth anniversary year of this event. The talk will take place on Friday 15 May at 7:30pm; the talk is aimed at a general adult audience and has no admission fee.
