Updated: Feb 2012Jenga Pot
History
Jenga Pot is an active dig at the furthest downstream sink of Hutton Beck, approximately 400m downstream of Excalibur Pot. Digging has been ongoing at Jenga since 2008, with the discovery of several parallel water-worn cross rifts. However, unlike its upstream neighbour, major breakthroughs have not yet been forthcoming.
The full story of the digging at Jenga Pot can be found in our first journal.
Current work at Jenga
A huge amount of water sinks at Jenga and this has been shown to resurge at Bogg Hall Rising, implying a subterranean merger between the water from the River Dove, Excalibur Pot (and the upstream sinks of Hutton Beck) and Jenga Pot. There is therefore great hope that significant passage extends from Jenga, with a possible connection to Excalibur Pot via Screek Passage, shown by recent surveying work to be less than 150m away.
To date we have discovered four parallel water-worn rifts at Jenga, reaching a total depth of approximately 16m (the approximate depth of cave passage at Excalibur). Based on the extrapolation of the north to south dip of the limestone at Excalibur we anticipate having to reach depth of at least 25 m before cave passage is encountered at Jenga. Digging is slow and is hampered currently by extreme instability. Jenga is presently on hold to provide the time for one particular rift to settle and wash clean.
Survey
Jenga Pot has been surveyed, and its location included on the ‘master survey’ (which includes Excalibur Pot, Bogg Hall Rising, Hutton Beck and the River Dove). This data is not publicly available however if you have a particular interest then please do get in touch.
Access
Jenga lies on a private estate and there is no access except for our digging team. If you would like to accompany us to see Jenga then please get in touch.
