After diving in Millbrook Quarry for so long, I was pleasantly surprised – one could say shocked – at the clarity of the water in Lake Rawlings. It used to be a limestone quarry I think, but now its a scuba park. Its not very deep (65ft) but there is ALL KINDS of stuff to see and do down there! Living in Northern VA, its a bit of a haul to get there, but it certainly is worth it. Picks can be seen here, or click here to see some video!
