One of the earliest routes on peak limestone. A quarryman is said to have made an early ascent by driving spikes into the rock, but the first free ascent is attributed to Samuel Turner, though with the use of a top rope. The first lead is attributed to Siegfried Herford in 1914. [1] References[1] James Merriman Archer Thomson Rucksack Club Journal (1915) page 51-53 /library/7684/rucksack-club-journal-1915 |
