Castle Lake Viewpoint, Mt. St. Helens National Monument, Washington, July 8, 2007
The lake to the right is Castle Lake, which was created when Castle Creek was blocked by debris from the eruption of Mt. St. Helens. A spillway was built to relieve pressure on the natural dam. This hopefully will prevent a catastrophic failure that could devastate downstream communities.
