Subject notes
Over large areas of central and southern Scotland the movement of glaciers in the last Ice Age has converted the land surface into a series of linear swells and depressions that trend parallel to the last dominant direction of ice movement. In the Falkirk area that is west-southwest to east-northeast.

Where boulder clay is thickly plastered over a rock floor of low but probably irregular relief, it has been moulded by the former ice-sheets into swarms of whale-shaped mounds called drumlins (from the Gaelic, druim, a mound). The steeper slope faces into the direction of ice flow.
