Pottsburg Creek Spring is a 3rd magnitude spring, most likely originating from the intermediate aquifer. The spring is situated in a marshy and heavily wooded area on the bank of a tributary to Pottsburg Creek. The spring vent discharges from under a tangle of tree roots on the bank. The discharging water is murky with a strong sulfur smell. The spring pool is about 4 feet in diameter, and the run flows about 0.3 mile to Pottsburg Creek.
From Jacksonville, take I-95 south to US 90 E (Beach Blvd.). Turn east (right) from the exit ramp, and the spring is approximately 600 ft (182.9 m) southeast on the southwest (right) side of the boulevard. The spring vent is located beneath a tree in the bank of a small tributary of Pottsburg Creek.
