The lower part of the Slide Lake landslide has averaged 14 feet of movement per year between 2004 and 2009. The landslide occurred in the Tertiary-Cretaceous-age North Horn Formation, which is known for producing many large landslides. Near Joes Valley Reservoir, the 1.2 miles long landslide deflects Seely Creek.
