Rocks of the Mississippian Systemare locally exposed at the base of the 41.5bluffs. Present in ascending order are the 43.1Clore Formation, Degonia Sandstone, andKinkaid Limestone of the Chesterian Series(upper Mississippian). Outcrop areas of the 45.0Degonia Sandstone commonly contain 45.3slumped blocks of sandstone; the KinkaidLimestone and Clore Formation are corn- 48.3monly obscured by vegetation and loose rockdebris.Intersection, lllinois Routes 3 and 1151.

The CampbellWill Coal is in the Spoon Formation and maybe correlative with the Wise Ridge CoalMember.Enter Perry County. Settlers came to PerryCounty as early as 1799 from Kentucky,Tennessee, and Virginia. The county, foundedin 1$27, was named after Oliver Hazard Perry,a U.S. Navy Commodore who became famousas a commander of the fleet during the Battleof Lake Erie in 181 3. Coal mining is the mostimportant industry in the county. In 1977,about nine and one-half million tons of coalwere produced from five mines in PerryCounty, which was the highest level of productionfor any county in Illinois.Roadcut, both sides of road.
