This one-mile trail winds through an old clay mine, owned and operated byt the Parfet family from the 1870's to the 1990's. The signs along this trail help interpret the evidence left by dinosaurs, other animals and plants of Late Cretaceous time.

Trace fossils resulting from animal activity as well as leaf and log impressions are useful in reconstructing prehistoric environments.
