The Farm Creek Section, also known as the Farmdale Geologic Exposure, is a hillside near East Peoria, Illinois that clearly showed geological strata. It is nationally significant as one of the first exposed glacial stratifications in the United States to be scientifically documented. These Ice Age geological formations, with rock layers representing different periods of glaciation, had long been known and published in England, France, and Germany, but were not yet well known in North America. Geologist Frank Leverett 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.
