A guided excursion round the geology of Islay – David Webster

The island of Islay is a treasure trove of geological sites. We will visit the “Billion Year Gap”, look through a “window” at the basement underlying most of the Grampian Highlands, see signs of “Snowball Earth”, and discover the best evidence in the British Isles of Precambrian life. With the occasional diversion to mineral sites and whisky distilleries.

Our guide, David Webster, has a degree in geology from Oxford University, an MSc from Stockholm, and worked for many years in the oil industry. Now actively retired, he has built a house on Islay, and is the co-author of “A Guide to the Geology of Islay”.
