A valley in NE Angus, Glen Lethnot is located to the northwest of Brechin between Glen Clova to the west and Glen Esk to the east. The glen, which seems to have lost its name on the majority of modern maps, contains the Water of Saughs, which becomes the West Water in its lower reaches. The Glen extends east and then southeast from Ben Tirran (896m / 2941 feet) to meet the Valley of Strathmore to the southeast of Edzell.
