Fossil bones of a mastodon are recovered from Wakulla Spring. The fossils were later articulated and the skeleton is currently on display at the R.A. Gray Building in the Museum of Florida History in Tallahassee. 1930s- Glass bottom boats became widely used to enhance the Silver Springs attraction. Herpetologist Ross Allen brings alligator, snake, and turtle shows to Silver Springs as part of the “Ross Allen’s Reptile Institute”.
The Wacissa Spring Group lies at the northern end of the Aucilla Wildlife Management Area in Jefferson
County and forms the headwaters of the Wacissa River. Over twenty springs form a cluster that runs
along the river. A public boat ramp allows for easy access to the core of the spring cluster. This dense
core contains Log, Thomas, Wacissa #1-4, and Acuilla springs, which together form a large bowl of fast-
flowing water. Along the run, large patches of Coontail compete with beds of Hydrilla beneath the clear
water. The combined magnitude and isolation of the Wacissa springs make the location one of the most
pristine in the state, earning the system a spot on the list of OFSs despite none of the individual springs
flowing at the first magnitude.
