'{{For|the Illinois wine region|Shawnee Hills AVA}} {{unreferenced|date=May 2010}} [[File:Garden_of_the_Gods_Sunset.jpg|thumb|''Garden of the Gods'' in the [[Shawnee National Forest]]]] The '''Shawnee Hills''' is a region of Southern [[Illinois]] that rests mainly in an east-west arc roughly following the outline of the southern end of the [[Geology of Illinois|Illinois Basin]]. Whereas [[Mississippi]]an and [[Pennsylvania]] Age rock layers are deep beneath the surface in central Illinois, these strata pierce the surface in southern Illinois. The Shawnee Hills are surface expressions of the more weather resistant limestone and [[sandstone]] layers. Within the Shawnee Hills, [[limestone]] is extensively quarried from outcrops, while both north and south of the Shawnee Hills, coal is mined by surface techniques on shallow coal seams near the edges of the Illinois Basin and by deep mining techniques in the deeper parts of the Basin. Additionally, extensive faulting in and around the Shawnee Hills occurred due to deep [[tectonic]] activities and formed sites for deposition of [[fluorite]], a mineral used for production of the element [[fluorine]]. At one time, about 80% of the world's fluorspar (the limestone ore containing [[fluorite]]) was mined near the towns of Rosiclare and Cave in Rock. A large portion of the Shawnee Hills lies within the [[Shawnee National Forest]]; one of the largest protected Federal forests in the [[United States]]. The beauty of the Shawnee Hills, the Shawnee National Forest, and the [[Ohio River Valley]] make the area a prime tourist destination. Though the Shawnee Hills are commonly called the "Illinois Ozarks," they are generally not considered part of the true [[The Ozarks|Ozarks]]. ==See also== *[[Ohio River]] *[[Shawnee National Forest]] *[[Dixon Springs State Park]] *[[Cave-in-Rock State Park]] *[[Trail of Tears State Forest]] ==References== <references/> {{coord|37|30|N|88|40|W|display=title}} [[Category:Geology of Illinois]] [[Category:Little Egypt]] [[Category:Landforms of Illinois]]'
