| Caption: | Glacial striae and roche moutonnee at Rowardennan Pier, Loch Lomond, Stirlingshire. |
| Description: | Deep glacial striae and grooves trending south-south-east showing the erosional power of the ice sheets in Loch Lomond. The ice moved up the gentle slope towards the south-south-east. The steep broken end of the roche moutonnee lies on the lee-side. The smooth side would face the ice. The rocks are strongly deformed steeply dipping Dalradian (Precambrian) turbiditic arenites (a detrital rock, typically a sandstone) and wackes (an arenite that is poorly sorted and ill-graded) with minor semipelitic units. The strike of the rocks is east-north-east. Scotland has undergone many glaciations over the last 1.8 million years, the last being the Devensian (Late-Glacial) Loch Lomond Stadial 10,000-11,000 BP (before present). Glacial striae and roche moutonnee are common erosional features caused by ice scouring. Both features are used for determining the direction of ice flow. |
