The well-weathered granite on this craggy (and definitely not “smooth”) hilltop is part of a batholith formed near the end of the Paleozoic Variscan Orogeny.
At about 400 meters, the peak is the second-highest point — after a neighboring prominence called Brown Willy — in a region comprising the far southwestern part of its host nation, and which is known for its beaches and chickens (although not the “game hen” variety popularized in the U.S.).
Answer: The weathered granite of Rough Tor on Bodmin Moor in Cornwall, England, is part of a batholith formed near the end of the Paleozoic Variscan Orogeny. Stone enclosures and hut circles attest to successive inhabitations, dating back to at least the Neolithic, of both the hilltop and its surroundings. Photo is by Leah Silverwood.
