Remember the whirlpool photo from a while back? It’s starting to look a lot like a glory hole. The kind that Monticello Dam in California has.
This shot is of the Great Blue Hole in Belize, a natural sinkhole that’s about 1000 feet across and 300 feet deep. Great for scuba diving.
There are also other spectacular holes featured on the site. And we don’t mean anything naughty by that.
