Strathblane divides the Kilpatricks from the Campsie Fells to the east, while to the north is part of the Loch Lomond and the Trossachs National Park.
To west and south the hills are fringed by the settlements of Balloch, Dumbarton, Milton, Bowling, Old Kilpatrick, Clydebank, Bearsden and Milngavie.
During an ice age, a glacier slowly undermined the crag, opening up cracks in the rock and causing this chasm to form.
The chambered cairn at Carnhowit is situated on the plateau top near the edge of Cochno Loch, at a height of 275 metres (902 ft).
Duncolm, the highest point of the range, is also the only Marilyn in the Kilpatricks, having a relative height of over 150 metres (490 ft).
