Farm Creek Section

Also known as: Farm Creek/Farmdale Geologic Exposure
S side of Farm Cr., East Peoria, Illinois



Frank Leverett, one of America's foremost glacial geologists, discovered this exposed face of a hill with its clearly defined stratifications in 1879 and described and pictured it in his monograph The Illinois Glacial Lobe in 1899. The site was used to help formulate regional and national stratigraphic classifications and has figured prominently in the study and development of glacial geology. -- National Historic Landmark statement of significance, December 9, 1997
