Hob, I agree, cup marks are widespread and consistent, and probably go way back.

There is a relatively new discovery not far from me. The Langdale Boulders are located halfway down the Great Langdale valley from Ambleside in Cumbria. They can be seen just past Chapel Stile, on the left hand side of the road, just over a stone wall. They are used by local rock climbers as a practice area,.

Currently there is some debate about banning the climbers, as the cup and ring marks may get eroded.

There are a surprising number of cup and ring marks, and when you see them it makes you wonder why they weren't discovered earlier.

At the head of the valley is the Pike of Stickle stone axe "factory". Axes from this site have been discovered all over Britain and Ireland.
