Surely not. Were Bleausards really climbing sit-starts on obscure boulders in obscure areas in the late 70s?
Of only tangential relevance, but people obsessing over weird bits of rock is older than you might think.
Gremlin's Wall, E4 6b, Ilkley Rocky Valley, unstarred. Climb
Flake Climb but boldly venture up the wall (about 3m tall) right of the final flake. FA Roy Heilds 1953.
A very significant lead by a local expert who spent the summer bivouacking in The Valley. Probably the hardest on gritstone anywhere at the time, it was dismissed by many who thought it impossible for the day and was omitted in the 1961 guidebook until its rediscovery by Al Manson in 1977.
Maybe Heilds was the Gaskins of his day? I've gone up to lead it and been pretty sure I'd do it but didn't think the risk of hitting my ankles on the ledge you climb above was worth the 0-star reward. Did it with a rope above after and it's very obvious what you have to do and not massively hard, so could be top end 6a/low end 6b. Regardless, very impressive for the early 1950s! It's really uninspiring but obviously Heilds could see that it would go and couldn't get the idea out of his head.
