This 2002 debris slide in the upper Muddy Fork valley and the scarring from the Nov. 2006 50-year flood all along the valley demonstrate the unstable nature of the pyroclastic volcanic mudflow here from the late 1700's. The box just upstream to the SE is the source area for most of the material deposited here in 2002.
