Martha's Quarry, Lebanon

Martha's Quarry is located about 30 minutes east of Nashville TN off of I-40. Check their website http://www.marthasquarry.com for details / maps / directions / etc. Quarry fee was about $15. A really neat dive as all the Quarry rocker crusher buildings and conveyer belts are still there and underwater. Also freshwater fish that love feeding. Not much in the way of facilities besides a picnic pavilion and a porta potty. Sometimes there are air fills via diesel compressor, but highly recommend taking extra tanks instead.
