The p6 lands in Northern Powerhouse, a further section of horizontal passage. It begins with two parallel passages, both tight but the R is easier (the L passage has a QMB climb off on the L, though this may simply loop back to the chamber you have just come from). These two passages re-join and, shortly after, you arrive at a balcony looking out onto a large, wet pitch the small L descending passage immediately before the balcony soon ends whilst an easy-to-miss c4 on the R a few metres before the balcony leads to a second balcony which overlooks the same big pitch. This Northern Powerhouse pitch descends 50m - care, loose rocks - to a wet chamber. From this chamber a c10 leads to an aven.
-The main way on from the balcony above the Northern Powerhouse pitch is to traverse (care, loose rocks) along the L wall then to ascend a short, awkward pitch (RIG12-06, see rigging guide) to reach the upper part of the chamber above the big pitch and the start of Medusa's Maze. This upper chamber was originally accessed by a climb on the R wall then a squeeze through loose boulders - not recommended. From this upper chamber a passage leads off the L wall to a pitch then to Gorgon's Lair - this is more easily reached via the main route, see below. The main passage continues W out of the chamber via a c5 down. This is easiest to descend by climbing past boulders on the R wall - a R here quickly loops back to the main passage further down. The main passage soon reaches a 4 way junction at PT30. Ahead quickly leads to a pitch, QM2019-B Is this really still an undescended QMB?. L enters a low, wide room, Gorgon's Lair, which has a draughting QMA on the far wall. The main route is R and this immediately goes to a T-junction. R here loops back to where you have come from.Go L and follow the main walking route, stepping over a small stream and ignoring minor R passages.Rest of the description needs writing from here
