Climbing history
The obvious traditional climbing route up the deep ninety-degree angled corner resisted attempts for many years until it was climbed by Joe Brown in 1952, and called Cenotaph Corner, and is regarded as one of Britain's most famous rock climbing routes.The outcrop is an important rock climbing venue in Britain, and the corner includes some of the famous traditional climbing routes in British rock climbing history, including Cemetery Gates by Don Whillans in 1951, Left Wall by Ron Moseley in 1956, Right Wall by Pete Livesey in 1974, and Lord of the Flies by Ron Fawcett in 1979. It also includes some of the most intimidating traditional climbs in Britain, such as Steve Mayer's 1992 climb, Nightmayer, from which climbers risk very large falls.
