Dry Dredgers Field Trip
April 23, 2011
Richmond, Indiana
Whitewater Formation, Late Ordovician Period

The Dry Dredgers were treated to a warm spring morning without rain that day. That spring had the most rain on record in our area. In fact, once 2011 had ended, it was known as the year with the most rain in recorded Cincinnati history. 

The site chosen to that day had not been visited since 2002. It exposes the Whitewater formation of the Richmondian Stage (no coincidence here).

Fossils found that day

The best finds of the day were two examples of a  rare Echinoderm called a Cyclocystoid.
