Holey Karst Batman!

Get it, because there's a hole . . . in the karst . . . wow, I've been in China too long. ANYWAY, this karst is pretty cool for a couple reasons. There is the aforementioned hole, slightly obscured by a tree. This karst is also an island, albeit a small one and very near land. It's also right next to the Banyan tree, which is how I stumbled across it.
