Fossiliferous shale

Above the shale and limestone is a gravel deposit that was laid down not much over 100 thousand years ago, during the waning stages of Illinoian glaciation during the Ice Age. The line of contact between the gravel deposit above and the shale below thus represents a time gap of immense duration. Such a time-loss line is called an hiatus.

Limestone is dark gray to very light gray, yellowish gray, very thin bedded to massive bedded, and fossiliferous; locally the thin bedds are argillaceous other beds are oolitic and a few contain chert.
