Scenic overlooks in Fall Creek Falls State Park provided ideal opportunities to observe the stratigraphy of the Cumberland Plateau and to witness the effects of the geomorphological processes at work along its western escarpment.
With a height of 256 feet, Fall Creek Falls is reportedly the highest aboveground waterfall in the eastern United States.

Using geologic maps, geomorphic features observed from the overlooks were related to the development of karst features along the western escarpment of the Cumberland Plateau.
The group enjoyed lunch on the rocks (Mississippian-age Monteagle Limestone) in preparation for going underground.

The following photos show trip participants getting "between a rock and a hard place" to explore the geology beneath the Cumberland Plateau.
