Glenthorne (grid reference SS800497) is a 13.3 hectare geological Site of Special Scientific Interest in the parish of Oare within the Exmoor National Park, on the border of Somerset and Devon, notified in 1989.
Glenthorne is a Geological Conservation Review site because of the Trentishoe Formation of the Hangman Sandstone Group. The Hangman Sandstone represents the Middle Devonian sequence of North Devon and Somerset.[1] These are unusual freshwater deposits in the Hangman Grits, which were mainly formed in desert conditions.[2]
