Ben Lomond, 974m, 3194ft Beinn Laomainn, "The Beacon Hill" Sitting on the peak of Ben Lomond at 974m above sea level [1] it is difficult to imagine how climate change will affect this, the most southerly Munro [2] , and the surrounding landscape.

Perhaps fires were once lit on its summit, linking it with a network of similar beacons throughout Celtic Britain, or it may simply be due to its prominence, visible over large areas of the lowlands - a symbol of what lies beyond.
