Grin and Go30m E4 6a ***. Tess Fryer, Ian Taylor. 12 Jul 2013.Start up a crack-line right of an imbedded pinnacle, then move left and up to a ledge. Continue directly to gain the main left-trending crack, which is followed to a rest below the final tower. Go steeply up to, then round the right side of a roof to a strenuous finish. A classic.
