These are views from the Visitor Center.
These are inside the Visitor Center. The VC has a short movie about the building of the dam and the effects of the two floods in uncovering the Denovian Fossil Field. The fossil field is a big attraction.
My desk is above left. Above right is the view from the door. The theater is through the door in the back. There are a lot of stuffed animals! There is a touching table with pelts and bones, and a touching table of fossils taken from the gorge and other Iowa quarries. To the left is a picture of my friend Ranger Pat.
This is a video of the spillway during the 1993 flood on You Tube from an individual. https://www.youtube.com/watch?v=sfk5VBoa0SQ. I can’t locate the Corps video shown in the VC. Perhaps it is a government secret!!

These are pictures of fossils in the VC.
These are two examples of crinoids from the Devonian era.
Crinoids are marine animals. The name comes from the Greek word krinon, “a lily”, and eidos, “form”. They live in both shallow water and in depths as great as 30,000 feet. Those crinoids which in their adult form are attached to the sea bottom by a stalk are commonly called sea lilies. The unstalked forms are called feather stars or comatulids. (Wikipedia)
In the center (of the picture on the left) is the dorsal plate of a Dunkleoteus. Dunkleosteus is a fish that existed during the Late Devonian period, about 358–382 million years ago. The name Dunkleosteus combines the Greek osteus, meaning “bone”, and Dunkle, in honor of David Dunkle of the Cleveland Museum of Natural History. This fossil is from one that was probably 5 feet in length. They got as big as school buses and could dislocate their jaws to eat things larger than themselves.
The picture on the right is a recreation of the Dunkleosteus with a diorama in the back. This picture is courtesy of the Vienna Museum of Natural History.
Below are pictures from the beach. These were taken in May. Nice clean beach!!
I really enjoyed my time here. I wish the Visitor Center had been busier, but I met some VERY interesting people. It is nice to volunteer 20 hours a week and receive a full hook-up site in exchange. Free electricity made it much easier to run the AC during the unseasonably HOT days.
