Mount St. Helens crater and steaming lava dome in winter
A brave volcanologist flying into the crater of Mount St. Helens for the first time!
Thrust faults in the southwest crater floor of Mount St. Helens, in summer of 1981. Talus from lava dome is at top of photo, ash covered snow from avalanches off the crater walls is at bottom. Largest block at center top of the photo is about the size of a house; fault scarps are 1-2 m high. (Photo by Don Swanson, summer 1981).
Lava fountains at night on Kilauea's east rift zone feed a lava flow that travels downslope from right to left before it dives back down into a gapping crack, from which fume rises (at far left). Note tree molds in the foreground venting burning gasses where a forest was overrun by lava earlier in the day (Jan 6, 1993).
