Crawl space.

The Bone caves near Inchnadamph are wonderful. They were explored by archaeologists in the late 1800's and lynx bones and wolf bones were found. This short tunnel between two caves was carved by water and is just big enough for a small person like me to crawl through, as long as you don't mind getting a big grubby.

Just one Corbett today before Davy buzzed us down the road.

Thanks for driving Davy, you are a hero.
