The Frozen Deep Trip and Dig June2019
« on: June 26, 2019, 11:12:18 am »
A welcome return to TFD and the start of a new dig in the fault under Ascension. Seems to draught a bit so you never know.


One side of the great arch by the drinking station. Dig up to left.

Mr O'Doc is giving his theory of the Cheddar Master Cave again.

The dig follows an undercut in the chamber wall. Basically a capping job.

Usual rushed photos on the old TG2
Camera in flash exclusion box for large areas. One hand held Yongnuo YN660. One placed out of view. Set at S1, 1/4 with 28mm spread which roughly is correct for 20m distance shots.

Please note. This is a project that started with an observation made in 2012. We still have to tape a route to the dig site and it is an unstable boulder slope so visitors should keep away.. To the questioner regarding the theory on the master cave I suppose you could say like Fred Davies 'Caves are where you find em). My raison d'etre for this particular dig was that this end of the chamber shows evidence of most recent flow under the floor. It has slumped considerably consistent with material beneath being swept away. Also in direct line is Pickwick Passage, scene of obvious vadose activity at one time and now abandoned. Its upstream continuation is obstructed by the collapse chamber that is the Frozen Deep. It seems reasonable to assume there may be a fossil upstream continuation the other side of the Frozen Deep.  I think it unlikely it took the whole flow though as Pickwick Passage is not that big, it is probably either a tributary or a distribuary.

I'm sure there are lots of theories.

The problem is Mendip limestone is dipped and faulted and Cheddar Gorge is riven by faults. Wherever you dig you end in boulder chokes at some point viz. Bone Hole, Spider Hole, Reservoir Hole and Gough's Cave.
