Midnight Lightning is a problem on the Columbia Boulder in Camp 4 of Yosemite National Park. It has been described as the world's most famous bouldering problem.The route 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. The bolt was re-drawn in the same location a few days later.
