There is an old Quarry on the far side of White Cliff Park. White Cliff Park is near Grants Farm, not far from Crestwood in St. Louis. The quarry is extremely small. I heard that 20 years ago you could dive it. I was talking with somone who claims to have done his open water at White Cliff. True or not... I don't know? The quarry is fenced off, however, looks interesting. I often wonder about what it would be like to dive it and if it was ever open to divers? Appears that it would one of those dive sites, you might dive just to say you've been there. However, an exploratory dive would be cool.
