The Knobstone Trail (KT) is Indiana's longest footpath - a 58-mile backcountry-hiking trail passing through Clark State Forest, Elk Creek Public Fishing Area, and Jackson-Washington State Forest. These state resource properties contain more than 42,000 acres of rugged, forested land in Clark, Scott and Washington counties in southern Indiana. The trail extends from Deam Lake, just north of S.R. 60 in Clark County, to Delaney Park, just east of S.R. 135 in Washington County. The initial 32-mile segment of the trail was opened in 1980. The Indiana Department of Natural Resources has developed the Knobstone Trail as a cooperative effort between the Divisions of Fish and Wildlife, Forestry and Outdoor Recreation. The Division of Outdoor Recreation's Streams and Trails Section coordinates development and maintenance of the trail. The Nature Conservancy has helped acquire land necessary to complete the trail corridor. Construction and maintenance of the trail has been aided by many hours of volunteer work donated by various hiking clubs and other groups. Much of the initial trail construction was accomplished through the Young Adult Conservation Corps program. The Knobstone Trail passes primarily through state forests, which are managed for "multiple use" to obtain maximum benefits from recreation, timber and wildlife production, and watershed protection. They are open to the public for hunting during season, and are managed actively to increase the fish and wildlife population. The harvesting of timber provides valuable income for the state of Indiana. Timber management and harvesting also provide diverse cover and food necessary for the perpetuation of many game and non-game animal species, and helps ensure that our forest resources will be available for future generations. The trail traverses land with extreme relief distinguished by narrow, relatively flat-topped ridges typical of the Knobstone Escarpment - a knobby slope between the Norman Upland and Scottsburg Lowland, two of southern Indiana's natural land regions. The Knobstone Escarpment is one of Indiana's most scenic areas, rising more than 300 feet above low-lying farmland in some areas as it snakes northward from near the Ohio River to just south of Martinsville. A central upland, mixed hardwood forest (oak-hickory and beech-maple association) dominates much of the escarpment. "Knobstone" shale, which is actually a combination of weathered brown shale, sandstone and siltstone, is common in the area and gives the escarpment its name.
