After enough good weather in the Hepste valley in South Wales Andy and Colin thought Tucks Rift might be in condition. This is a long term project that has resulted in us finding about 100 m of previously unexplored passage and one aven with an impassable surface connection. At the end of this passage there is a possible dig site but it is beyond a couple of interesting constrictions so we have been looking at other possibilities in the system. Our chosen site is at the end of downstream sump 2; originally explored by Martyn Farr the known limit of the sump is described as being low over cobbles to a sharp right hand bend to a tight rift.
On the day we found that the dry spell had been long enough for the vis to clear and that the bad weather so far this year had done considerable damage to the dive line. Repair work on the line through S1 and the start of S2 took us to the point where our last dive in the cave had been halted by flood debris. The latest floods had washed the passage clear and line was laid into the continuation of S2 in good vis until the dive was turned on air margins after 45 minutes. All old damaged line was removed and both divers noted a booming noise at one point in the sump which could indicate a water surface being hit by a waterfall.
The picture was taken in the air bell between S1 and S2 with a bundle of old line in the divers right hand.
