Description: North slopes of Lammermuir Hills 1.5 km. east-north-east of Blegbie Farm. East Lothian. View looking south-west. Glacial drainage channels. A prominent channel is seen extending from the central middle distance to the left foreground. The water flow in the channel was from south-west to north-east. The mouth of another prominent channel is seen in the right foreground. Both channels are cut in Ordovician greywackes and shales. During deglaciation as the climate improved, the ice retreated and melted leaving ice-free ground along the slopes of the Lammermuir Hills. Large volumes of glacial meltwater were released to cut numerous glacial meltwater channels. Ice lying in the low ground blocked the river valleys, so damming the meltwaters which were forced to cut new channels along the ice margin and across cols into other valleys.
