Inchcailloch Island, Loch Lomond

So, we were going on a little hike in Loch Lomond, which you'll know is Scotland's big national park. We took this tiny little ferry boat out to an ancient island. Beautiful day, but the fog was rolling in so we were pretty much the only ones on there. It's a bit creepy, and foggy and dark, but we hike the whole thing, couple hours.
We hike up to where a nunnery stood from 734AD, not much left but the foundation of the church covered in moss. The cemetery there is still sort of in use though, the last burial being in1947. or so we read on a information board nearby that told us that Scottish burials are no sober affair. It has been said that one one occasion that the attendants were so drunk from whisky, that they nearly for got to bury the body....
So, we're checking out all the ancient headstones, and mo spots, of all things, a geocache stuck in the foundation wall. Awesome!
As we are digging it out, my knees fell out from under me when I looked over the other side of the foundation wall.
