The walk began with Jura Quartzite, where the rock layers noticeably dip in a South East direction - meaning we were walking in the direction of younger days ahead! Here a rare form of kyanite mineral can be found. This Quartzite is what makes up the Paps of Jura.

Moving on, as well as examples of compressed sedimentary rock squashed to form slate, we were introduced to a new rock type - conglomerate - seen down by the lighthouse, identifiable by the small pebbles embedded in the layers.

Thanks to David Webster for this wonderful walk and helping us get our heads around all the geological terms and timescales! A fascinating walk discovering Islay's ancient landscape. - Lorna
