Index card: View looking upstream at the Smith Creek drainage basin. Smith Creek, a tributary to Muddy River, was inundated by several feet of mud, and phreatic eruptions can be seen occurring through the mudflow. Note the trees stripped from the hills and fires burning on the hills; also the deposit of trees on and through the mudflow. On the left of the slide you can see water beginning to flow over the surface of the newly deposited mudflow. Skamania County, Washington. May 19, 1980.
