- Devonian Fossil Gorge Devonian Fossil Gorge is the result of the prolonged overflow of the Coralville Reservoir Spillway between July 5 and August 2, 1993. This area is just south of the Coralville Dam (near Iowa City), managed by the Army Corps of Engineers.
- Stainbrook Geologic Preserve The most abundant fossils in this area are crinoid stem fragments; these look like small washers such as you might find in a hardware store, and there are some layers exposed in the roadcut that are almost solidly made of these.
