Volcanic eruptions don't only destroy. Sometimes they also create, as happened here: Debris from the eruption blocked the normal outflow of Coldwater Creek, which ultimately created this beautiful lake.

If you'd like to avoid crowds around the other side of Coldwater Lake, starting here and hiking northeast gets you some nice views over the lake from elevation. Or, if you don't mind walking beside the road for a short distance, you can use this trailhead to link a complete, challenging loop around the lake.

All in all, the Boundary Trail runs some 57 miles, mostly east-west along the north side of Mount St. Helens. Shorter chunks of it, like this one, are handy for linking trailheads or completing trail loops.

This so graceful lake looks like it has existed forever. However, it only emerged in 1980 after the eruption, as a landslide prevented the outflow. A lake was created from the former canyon, the development of which has been very well researched. Today even rainbow trout swim in the clear water.
