Geology Ramble - Kilchiaran 20th July

A small band of budding geologists gathered for an insight into Islay geology, super old rocks and a fascinating explanation of how they were formed and how they got here, once formed over the South pole! David Webster provided the answers and managed to make confused brains understand how it all fitted together. A million years difference in the geology of the rocks south of Kilchiaran Bay and those to the north.
