The Shawnee National Forest encompasses the western portion of this 2015 study, dominated by the prominent elevation of Bald Knob and the winding course of Clear Cr. This Southern Illinois landscape is defined by its deep ridges and hollows, including Ranbarger Hollow and Milligan Hill, which separate the small settlements and orchards of the region. The map documents the critical water infrastructure of the Alto Pass Reservoir and numerous headwater creeks like Cave Cr and Hutchins Cr that drain the high ground along the Jackson and Union County line.
