Midnight Lightning (bouldering)

Midnight Lightning is a bouldering problem on the Columbia Boulder in Camp 4 of Yosemite National Park. It has been described as the world's most famous bouldering problem.[1] The first ascent was by Ron Kauk in 1978; the first female ascent was by Lynn Hill in 1998.[2] Sam Moses, writing in Sports Illustrated said the most difficult move on Midnight lightning is a "spider-monkey swing 15 feet (4.6 metres) off the ground. The climber must suspend himself by the fingertips of his left hand, swing around a ledge of rock and propel himself far enough up, about four feet, to grab a precarious fingertip hold with his right hand. To do that he has to create momentum from stillness."[3]

The iconic chalk lightning bolt was scrubbed off the face of the boulder once again on 5/28/19 by an unknown person.

The problem had been easily identified by a chalk lightning bolt drawn by John Bachar in 1978 while attempting the problem with John Yablonski and Ron Kauk. In May 2013, the iconic chalk lightning bolt was scrubbed off the face of the boulder[1] by James Lucas[citation needed]. The bolt was re-drawn in the same location a few days later.[4] The bolt was again erased on 5/28/19 by an unknown person.[original research?] The climb is rated at V8 on the Hueco scale of difficulty.[5]
