The route starts in a crack behind the free standing pillar on the left end of the Winter Wall. Follow an arching/thinning crack, (that parallels The Arch - but slightly higher) to the same shared anchors.
Look for the detached, free-standing pillar at the left end of the Winter Wall. Start behind the pillar.
Trad rack (small gear helpful) and a few long runners. Anchors at the top.
