Excellent examples of glacial meltwater channels occur on the Torphichen Hill and Gormyre Hills. Glacial meltwater has exploited weaknesses along faults in the quartz-dolerite sill, incising deep channels over the high ground. The remains of a fort on the southernmost hill are a Scheduled Ancient Monument.
