Title: BARREN LANDSCAPE PRODUCED BY ERUPTION
Caption: Desolate and barren landscape produced by the May 18, 1980, eruption of Mount St. Helens. A debris-avalanche and debris-flow deposit fills the North Fork of the Toutle River valley in the lower half of the photograph. Slopes in the right half of the photograph that appear to be sparsely forested are actually areas with scorched, but still standing, trees that were seared by the lateral blast. (John S. Shelton)
