Mt. St. Helens is the most active volcano in the Cascade range. Though the mountain is most famous for its 1982 eruption, where it lost 1300 vertical feet and nearly a third of its mass, Mt. St. Helens was fully active as recently as 2008.
I had made two previous, unsuccessful attempt at Mt. St. Helens. Each time we were forced to turn back by whiteout conditions. Originally we scheduled this trip for the following day. But, seeing the onset of a new weather system, we bought some resale permits online and headed to the mountain a day early. I did not want to get skunked again.
