Rock3660035

Day 1 : In 2010 I endeavoured to photograph a rock every day – project Rock365.  How to better this? Wait for a leap year and start Rock366!

This the the Buttermere and Ennerdale Granophyre – a granophyric microgranite from the shores of Buttermere in the Lake District. It was intruded as a laccolith, just over 1 kilometre thick, in the Late Ordovician.
