Report of Investigations Number
The site under investigation, Bonnie Creek (21C4-46), is located in the Northfield of Consolidation Coal Company's Burning Star Mine# 4, Perry County, Illinois. Lying within the southern portion of the Till Plains Division, known as the Mt. Vernon Hill Country, the Northfield exhibits a mature landscape of gently rolling hills and broad alluvial valleys through which flow Galum Creek and its major tributaries, Rock Fork and Bonnie creeks. Galum Creek, in turn, is tributary to the Big Muddy River of southern Illinois.
