YES TOR

'Yes Tor' is the second highest point on Dartmoor, Devon, at 619 m (2,031 ft) above sea level. Together with nearby High Willhays they are the only two peaks above 2,000 feet south of the English Peak District National Park, which makes them mountains.
It lies within a British Army firing range and safe access is only possible on days or nights when firing is not taking place. See the current Dartmoor Firing Notice.[1]
Yes Tor was also the original inspiration for the name of the Yes album ''Tormato''.
