Sadly scuba diving is no longer allowed at the Atlantic Quarry in Atlantic, IA. There is a locked gate at the entrance along with signs saying "These Gates Close Daily at 4:30PM", "Danger No Trespassing" and "Rock Quarries are not Playgrounds - Stay Out - Stay Alive - Iowa Limestone Producers Association." Our club had a great run at the quarry and a huge thank you to Schildberg Construction for allowing the club to dive at the quarry for so many years.
