What makes this site worth diving
White Star Quarry in Gibsonburg, Ohio, is a spring-fed limestone quarry used for scuba training and local recreational diving. Depths across the main floor average 12 meters, with pockets reaching 20 meters. Submerged guide lines connect sunken attractions, including a small airplane, boats, automobiles, and training platforms. Summer thermoclines drop water temperatures sharply below 6 meters.
