Abstract

Peat discovered below drift near Titusville, Pennsylvania, formerly called "inner Illinoian," has a carbon-14 age of 31,400 ± 2,100 years. The overlying drift, herein named Titusville Till, is therefore not Illinoian but is "late early Wisconsinan" or late Altonian of the Lake Michigan lobe classification.
