Evidence of strong earthquake shaking in the lower Wabash Valley from prehistoric liquefaction features
Earthquake-induced liquefaction features in Holocene sediments provide evidence of strong prehistoric shaking, magnitude m b 6.2 to 6.7, in the Wabash Valley bordering Indiana and Illinois. The source of the one or more earthquakes responsible was almost certainly in or near the Wabash Valley. The largest event is interpreted to have occurred between 7500 and 1500 years ago on the basis of archeological, pedological, and stratigraphic relations.

Artifact from deposits of mid-Wisconsin age in Illinois
Discovery of an artifact of human manufacture imbedded in Roxana loess, classed as Altonian substage of the Wisconsin stage of the Pleistocene, of an age of 35,000 to 40,000 years, contributes to the determination of the age of man in the New World.
