Midnight Lightning | 7B Boulder problem at Camp 4 Boulders

United States / California / Mariposa County

Allegedly conceptualised by John Yablonski whilst under the influence of LSD. Named after the Jimi Hendrix song as it was considered as unlikely as lightning striking at midnight.

Climber Style Ascent Date Suggested Grade
First ascent.

Ron uses a slightly different sequence to usual: instead of pressing fully in to the mantel he gets half way in to it and then uses a little crimp for the left hand.

Second ascent.

Bachar drew the original and iconic lightning bolt on the problem while working it with Ron Kauk and John Yabolinski in 1978. He would climb the problem regularly for an audience in Camp 4 at a time when no-one other than he and Kauk had managed it.
