 The lower boundary of this sequence is a thrust fault which carries the slates up over the Hangman Grits.The overlying Lester Slates-and-Sandstones run from Widmouth Head, beneath the village of Combe Martin and on in a SSE direction to near Parracombe.The Combe Martin Slates in turn extend from Beacon Point at Hele in a narrowing outcrop to Pinkworthy Pond and beyond.
