This was probably one of the prettiest "haunts" we ever came across. What used to be known as "Black's Ravine" is now called The Devil's Punchbowl. This giant "scoop" in the ground as we would like to call it, was a result from a sea deposit which formed up about 4.6 billion years ago. About 500 million years ago, an ancient sea laid down sediments and buried itself into sandstone rock.
There have been reports of gnomes scurrying up the side walls or rock or thru the tunnel along the side of the bowl. Also water collected has remained clear and cold no matter where you put it or what temperature it is outside.
