Sandbag Spring is at the head of a 40 foot run on the west side of the Chipola River approximately 1.9 miles north of the Highway 90 bridge. The vent is an opening approximately four feet wide in the bottom of a steep-sided limestone pool approximately 20 feet in diameter and 10 feet deep. The vent and pool appear to have been artificially enlarged. There is no visible surface boil. The spring is on private property very close to a private residence. The banks have been modified with concrete to resemble a swimming pool deck with a dive platform directly over the vent.
