Biggs Marron

First climbed at A3/17 by Barry Biggs and Reg Marron, then in 2000 freed at grade 20 as Sewing of the Seam by Keith Riley and Rob Wigley. Follow the seam which forms a left-to-right diagonal between the two bolted routes. Gear is sparse at times, but the crux is well protected. Pitons were used during both recorded ascents.
