<p>Brimham Rocks, North Yorkshire, England. Showing the front (east) end of the narrow hole which goes right through the Great Cannon rock. It is less than 1ft diameter at the widest circumference. You can just see a speck of light at the end. The National Trust had no record of the original Great Cannon, but luckily the local climbing clubs retained the name. Great Cannon, Cannon Rock or The Cannon is the oldest known named rock on this SSSI site.

Showing hole at back (west side) of rock, which appears to go right through. This is possibly the other end of the hole which starts at the east side. You can see it at centre of image, between branches. It is about 8-0 feet off the ground at this end, so it is difficult to see through.
