Mendip Caves and their Risings

[whitelackington]

Coral Cave,
near Axbridge has perhaps the deepest natural, surface shaft on Mendip, the present bottom of the cave very occasionally in storm conditions floods to 25 feet depth, then the water drains away.
The bottom of the cave is only 75 above sea level and not far from the river Axe.
Does anybody know, does it drain straight into the river or does it come out at risings or both? :alien:

Gough's Cave

How deep does the deepest Gough's sump go, is the bottom much below sea level?

 

[mrodoc]

Wookey end is deeper than any of them being something like 90 metres water depth  - and that is measured by gauges normally calibrated for sea water.  I don't think the resurgence is that high above sealevel.

Gough's Cave

How deep does the deepest Gough's sump go, is the bottom much below sea level?

Mendip Underground gives sump 3 in Goughs as 55m deep, given that Goughs resurgence is at about 26m this means that the lowest measured place in sump 3 is about 29m (approx 100 ft) below sea level

Does whitelackington own his own copy of Mendip Underground? It might save a lot of bandwidth if he bought one.

 

[whitelackington]

Yes Graham, I do, I also own many other things but this is a cavers forum and we are here partly to postulate and partly to be shot down.
Get your gun

So why then do you keep asking questions whose answers are on a bookshelf behind you? That is not "postulating" that is idleness.

Don't expect any sensible answers then.

In the village where my father's house is, Hutton there is Mendips most Westerly Resurgence.
About 1/2 million gallons of water outflow in 24 hours, although, occasionally in drought it dries up.
Sometimes used for cave diving practise.
I belive this is Mendips greatest resurgence with NO KNOWN FEEDERS.
where are the barsteds?

where are the barsteds?

Aren't the Barsteds somewhere near the Malverns, or is it the Poldens?

No wonder there's been a water shortage! Has anyone told the water company that the big main through Mr Whitelackington Senior's village has fractured?

Unbeliveably the greedy water companies must have overlooked Ludwell, but that spring will undoubtedly have been the reason for the village origonally having been sited nearby.

"Thirsty" water companies?

Here's any easy quiz for the locals,
which Mendip Pot is also its own rising?

Here's any easy quiz for the locals,

Is it Mells River Sink, which is an "estoval" - karst terminology for a swallet/resurgence?

 

[cap n chris]

Easy?  :-\

Really?

Hi Les, that is not the one I was thinking of but bloody well done, I'll give it to u anyway.
Rest of u lot just keep on guessing.

I expect Mister Williams, that I have asked this before but it is preying on my mind.
If u could cast your mind back twenty thousand years,
when we have been told @ times the sea level was 100 metres or there abouts lower than it is now, do u think that Gough's cave for example would have still risen @ its present location.
Or I imagine it would have carried on , probally phreatically for a jolly long way , much nearer the sea,
before it rose.
If that is so, the cave there could be a monster tunnel, full of mud/water waiting to be partially eposed/explored?

 

[graham]

Although the Cheddar risings are (now) quite close to sea level, they are not controlled by sea level but by the level at which limestone is exposed from beneath the overlying superficial deposits. At times past, although sea levels may have been even lower, the resurgences were actually higher because greater amounts of superficial deposits abutted the Mendip massif, yet to be eroded away.
