Sissons (1958) on meltwater channels in East Lothian
Longyester meltwater channel system, with gravel workings
Definition: channel cut by glacial meltwater under, along and in front of an ice margin.
Complex systems of glacial meltwater channels form a striking element in the scenery of East Lothian. The channels were cut beneath and beside ice sheets and glaciers moving across the Forth lowlands. As the ice thinned and the flanks and summits of the Lammermuir Hills emerged, huge volumes of meltwater were generated. New channels were cut and old ones reoccupied. Enormous quantities of sand and gravel were transported and then deposited to form a range of fluvioglacial landforms.
