Underground Description
On the way back [from Tunnocks] I stumbled across a third cave - a shaft with a two second drop from a tennis ball sized/shaped piece of rock. The shaft was (about) wide enough to fit a small car into and I could not see the bottom as it was deep / steep sided. It is likely to be chossed up but remains undescended and is labelled with tag 2012-SW03.
