Between False Slab Buttress and Upper Buttress is a wide snow gully, which narrows to form a steep chimney between an undercut right wall and the turf bank to the left. In lean conditions the chockstone may be difficult. Requires a hard freeze and a large dump of snow. Sometimes forms a cornice at the top.
Cracking! Didn't expect to find such a good mountain-style gully two minutes from my house. Interesting chimney-climbing at the crux followed by an hour of cornice-tunneling. Quality stuff. Only a hill - Solo O/S - 01/Mar/10
