Geological Walk at port Ellen

Nice weather for a change. 12 folk met at the Co and on the way across the bay and out onto the Ard learnt about 600 million-year and 60 million-year old oceans, collisions and break-ups of ancient continents. plus a bit of metamorphism.
The ridges of the Ard are composed of harder meta-basite rocks and the interveening linear boggy bits are underlain softer meta-sediments. Good hiding places for illict whisky stills in days gone-bye. We finished off with the obligatory bit of audience-participation as we created a human timeline from the big-bang to the stone age.
