Glen Roy is famous for its parallel ‘roads’, three strikingly visible lines partly cut into the bedrock at heights between 250 and 330 metres, which were the source of a great deal of enquiry and debate in the development of geological thinking by many of the greatest minds of the nineteenth century. These ‘roads’ are the remnants of a glacial lake that existed in the glen during the last phase of glacial activity (the Loch Lomond Stadial, approximately 10,000 years ago). The three clearly distinct lines indicate three different levels of this glacial lake, each of which lasted long enough to form a shoreline and they are unique in Britain for their excellent preservation. There is growing concern that a recent proposal by Scottish Natural Heritage to remove National Nature Reserve (NNR) status from Glen Roy will lead to a deterioration in this unique site. RSGS and others have written to express our concern and to appeal for this status to be retained in order to continue to protect this site.
