The Orkney of today is formed out of the sediments of a great lake that once stretched across the north, from Caithness to Shetland and Norway. Howie Firth tells the story of the lake and the land that was formed from it, and the ages that followed, of ice and flood, of war and peace. The talk, hosted by Garve and Lochluichart WRI, was attended by over 20 people, several coming from the nearby village of Contin specially for the occasion.
