When is a volcano not a volcano? I’m sure there is a perfectly sound geological answer to that but I can’t be arsed to find out. Instead, I like to think I was standing on a volcano yesterday even though it hasn’t been active for over 400 million years ago in the Ordovician period. Croft Hill is certainly a feature that can be seen from kilometres away even though it is only 128 metres high.

Whenever I have made the trek to the top it also reminds my of the Arthur C. Clarke’s short story The Sentinel. This is credited as the inspiration for the Obelisk in 2001: A Space Odyssey. On a day like yesterday you can imagine all manor of things with the dramatic sky and low lying sun.
