The Parallel Roads of Glen Roy are one of Scotland's natural wonders. The origin of these remarkable shorelines on the hillsides of Glen Roy, Glen Gloy and Glen Spean has been a source of great fascination to local people, visitors and scientists alike - even attracting the interest of Charles Darwin. This book tells the story of how the Parallel Roads formed and reveals a fascinating picture of how ice age glaciers and ice dammed lakes shaped the landscape of the West Highlands.
