We slept in a bit on Day 13 and so we got off to a late start to Mt. St. Helens.
Last major eruption was in 1980 but there have been over 10,000 mini eruptions since then. The last “bigger” one was in 2004. You will know when there is a eruption as it sends out tremors. The volcano in 1980 swelled over 80 feet in just 3 days!!
