here's a reference to the "infamous" Generator Crack in 1973...
Generator Crack Area. In April 1971, Jerry Coe and I explored a hitherto hidden small 200-foot cliff band directly above the generator building of Generator Crack infamy. This cliff, characterized by knobs, has thus far yielded four fine short routes: The Electric Gully, Chimney for Two, Chickie Pie, and New Diversions (Claude Wreford-Brown also in ascent party). The latter two are exceptionally fine. All are in the F8 range.

I remember sacrificing many hours and much skin, on top-rope, in the fall of '70 to the Generator in an effort to learn the "ritual secrets' of Yosemite climbing.Even then it seemed to be a well-established climb. My efforts there, and similar ones on climbs such as Church Bowl Chimney Right (done wrong!!!!)had only temporary success, since when I next climbed in the Valley 2 years later, I had to start all over again, and still get stopped cold most of the time on the wide and the flared!!!!!
