Updated 30th October; 25th November 2013

An awkward sideways squeeze down ends at the head of a pitch. There is a bolt on the surface for a traverse line. A bedding plane just below the pitch head is full of fill with rifts connecting back to the main shaft. The main drop of 4m + 17m is split to avoid a rub point.
The floor can be followed down to holes between boulders - one can be followed down to another 5m pitch to a blind pit. A rift off the base of the main pitch leads to two pitches down on the right - only the first one was dropped as they connect. This drops 10m to the floor where rifts continue - too small, but taking the draught. The rift continues over the head of these pitches to a point where it narrows before possibly opening after a constriction.
