Pottsburg Creek Spring is a third-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.
