Jonesboro serves as a focal point for this survey of southern Illinois, anchored by the Union County Courthouse and its historic street grid. The neighboring city of Anna is equally prominent, featuring the Anna State Hospital Reservoir and a network of named local streets like E High St and W Davie St. The topography is defined by the sharp rise of Iron Mtn and the long spine of Atwood Ridge, both set within the protected boundaries of the Shawnee National Forest.
