In 2002, a tornado swept across Morgan County, devastating the community of Mossy Grove and wiping out some of trees in Lone Mountain State Forest. The tornado caused the closure of the Carl Black Spur trail which remains closed as of 2008. Forestry officials plan to have the Carl Black Spur trail open for the public again soon. The tornado opened up the opportunity for a new trail aptly named Twister Pass which runs from the South West trail up to Todds Landing. Southern pine beetle infestations in the 1970s and 1990s killed off a large number of the forest's pine trees, leaving mostly hardwoods.
