Had a look at this years ago, actually its quite interesting, it was first noticed by a local lad Robert Ashton when it was exposed by machines.
The large entrance leads through quite a big vestibule, which gradually decreases in height towards the back end, this in turn leads to a short stooping walk which emerges into a large chamber with various digs in the roof a further stretch of walking passage leads under a high aven with a small waterfall coming from an impenetrable inlet. just beyond, the passage rises to the top of a steep slope, an inlet on the left can be followed quite a way before becoming too tight.
Dropping down the steep slope a large stream is met which can be followed downstream for some distance to a sump, straight on at the bottom of the slope (upstream) a walking passage can be followed for quite a way under several avens which have all been climbed, one leads to another entrance but access is not allowed. the passage eventually splits one ends in a sump and the other goes to a high aven which has been climbed to various bits of passage, the main passage carries on to a duck, beyond this, the passage continues for some distance with various passages and chambers going off, ..... sorry I lied, its really a grotty Stoney Middleton remnant of silt filled phreatic tube that doesnt go anywhere, we called it Roberts Cave I dont think its worth digging, but there is a lot of stuff waiting to be found on that side of the valley, sorry about the wind up, does the description sound familiar anyone
