WARNING At the base of the dry waterfall in UPPER EASE GILL KIRK. Twin entrances behind large flakes on the south bank unite in a series of rifts and bedding planes. A shelf on the left leads to Shelf Sump. This can be easily syphoned as it is only 1m long and a short section of tight drafting rifts is being explored.
The main way on is on Fissure crawl into a descending bedding plane and a small passage lead to a 3m chockstone climb and a 14m spiraling pitch. From the foot of this leads to a climb down into a large passage. Upwards over boulders soon chokes, but the other branch descends through pools to a crawl over boulders into a wider section. The continuing wide passage lowers to a sump.This has been dug underwater for about 4m and the flooded passage continues for 37m to a junction with a larger passage. To the right and downstream another 20m of sump breaks out into dry passage Kirk pot II. This continues as walking passage for 65m to another sump. Sump 2 is 15m long to Kirk 3 another section of passage to a steep bank of cobbles at the top of which is the +15m high Terra Nova Aven. The far side of the cobble slope leads to a large black lake sump chamber. Right here is Scott's Pool a 28m deep flooded shaft and to the left is an impressive canal to Sump 3, which is only 1m long. A short section of canal leads to Sump 4. Sump 4 has been dived for 90m and is still going.
Left and upstream from the 37m junction in Sump 1 leads to a junction after 26m the lefthand passage soon chokes but the righthand one continues for over 30m to a low section immediately followed by a junction. To the left is blocked but is only 30m from PEGLEG POT. To the right a large passage with beautifully scalloped walls heads south for 100m and continues unexplored.
