The divers proceeded to the bottom of the pot to find to their dismay that the final sump reported in Northern Caves Vol. 1 p. 38 does not exist! The cave ends in a choke of muddy boulders. Returning to the bottom of the first pitch a search was made for the "inlet" sump. A likely-looking pool was dived in a side passage only to find that it was merely a flooded dig. The correct sump was finally located at the bottom of a ten foot climb in a narrow rift. R.J.S. dived and passed a squeeze to reach the air space reported to have been seen but not reached in the above reference. Ten feet of narrow rift led to a duck and further small air bell. Beyond this the rift closed down below water surface to impossible dimensions.
