The Pinnacles shown above are eroded remnants of old fumaroles that released gases through the ash flow tuff that erupted out of Mount Mazama.
Mount St. Helens was in late August and the night before the hike, it snowed on the mountain. I had no coat to wear, so I purchased this vest to keep me warm on the hike. Here I am standing at a rest stop about halfway up into the crater.
visitor's center was a car demolished by the blast from the volcano with a few of our group looking on. You can watch a video about the eruption produced by the USGS here. Don Swanson, who is featured in the video, was our guide up the mountain in 1993.
