Beinn Mheadhoin (1182m) - pronounced as ’Ben Vane’ - was formerly well known as producing smoky quartz, in the 19th century! I have been over it a couple of times but failed to find anything worth carrying out, except for one single beryl crystal on my first visit in 1994. Photo taken looking East at the mountain, with it’s distinctive ’tors’, in July 2006. (Author: Mike Wood)

Ben Loyal, Sutherland, Scotland The next day it was really sunny and I drove round to the east side of the mountain, which looks like this. The slopes are much more gentle but there is hardly any bare rock. The photo was taken from the top of Cnoc nan Cuilean (557m) which apparently is a distinctly different part of the syenite intrusion, containing more mafic minerals and elevated REE’s. I didn’t see anything worth jumping up and down about. Oh except perhaps an otter in the burn (stream) that I followed to get there. (Author: Mike Wood)
