 <h2>Big rift series</h2><p>A pitch of 23m has an inlet entering part way down, which makes the rest of this pitch and the following one of 19m unpleasant in wet weather. Two ways then lead on, either down with the water or by traversing round this drop to another passage.</p><p>Climbing down with the water leads to a short passage with the water in a rift below. Round a sharp corner is a short drop to the head of a larger rift. A 5m pitch down this leads to another rift which, in turn, leads out to the side of a large shaft. Stones dropped from a small hole in the corner of the passage above the 5m pitch also fall into this shaft. Laddering from the side, the pitch is 67m with a large ledge just above half-way, and is unpleasantly wet in poor weather. From the base of this pitch, the continuing rift/canyon trends south west and has pitches of 5, 9 and 8m before the other route drops in from above.</p><p>Over the traverse, a short pitch of 4.5m, followed by a short climb up, leads to the head of a pitch of 10m to a boulder floor. Two ways on from here are down through the boulders into a shaft, or across the shaft and into a narrow rift. The way through boulders soon chokes, but the narrow rift soon opens into a massive shaft of 100m with a rebelay roughly halfway. This drops directly into the rift reached by the original route.</p><p>Below the junction, the rift continues with a 5m climb and pitches of 5, 14 and 44m, this last pitch being quite wet and emerging into a massive cross-rift trending south east. The water disappears into the choked floor of this rift via a nasty wet crawl, rapidly becoming too small.</underground_description>
