This report focuses on the deposition of the clay-rich Lagro Formation north of the Wabash-Erie Channel in northeastern Indiana. We present initial depositional models for the Lagro Formation within a segment of the Wabash moraine in northwestern Allen County and two segments of the Salamonie moraine in Huntington County. The models are based on initial descriptions of three rotosonic cores—SC0801, SC0803, and SC0804—that were drilled by the Indiana Geological Survey in September 2008.
