Well, my work and the weather have conspired against me getting any new shots, so I'm afraid I'll have to resort to the archive like a few others.

This is a shot of the mountain Suilven, which is formed from Torridonian sandstone that is 1.2 billion years old according to radiometric dating. Furthermore, the paler grey bedrock in the middle distance is Lewisian gneiss which is at least 2.7 billion years old. I climbed it twenty years ago and I can tell you it's as steep as it looks. It has certainly stood the test of time better than I have.
