This site lies at the end of a track, about 50m up in the woods from 3 houses. The 6m diameter shaft has a bridge of boulders part way down that can be reached from a more westerly hole that descends on boulders. The main shaft has an encouraging rift down one side and appears to terminate the valley stream bed.
The site was partly explored a couple of weeks after the initial find: 30m down two pitches to a chamber. It was then possible to see down at least another 20m with the sound of water.
The site was pushed over a number of trips during Easter 2004.
The woods around the hole were searched for other sites in August 2013 but nothing of interest was found.

Description
A short entrance pitch series of 8m and 15m drops into a large chamber with several ways on.
1) Back under the pitch, a small climb leads to a possible chamber (not pushed)
2) Heading down slope and right leads to an obvious pitch of 10m. A climb over leads to two blind avens with water dripping in. The water sinks through a small hole through which a possible chamber can be seen.
3) Heading down slope to the left a series of holes are found in the floor, but these connect to the blind avens described above. A low crawl in the left hand wall near holes leads to a large rift system. A 35m pitch gains the floor of the rift. To the right of the pitch, climbing down through boulders, yields a 4m ladder pitch with the passage becoming very muddy. A breakdown chamber is shortly reached. Following the water course down to the right, leads to a tight drafting rift, too tight to push. A climb through a window above this rift, leads to a big aven, with a tight rift heading down. (Not pushed, very tight and committing).
Many routes exist in the breakdown, including one back to the 35m pitch. No continuation of the main rift was found in this area. To the left of the pitch, a traverse across reaches the floor. A small hole leads to a short passage heading down to a blind aven. A climb to the left above this was also blind.
Heading along the rift a climb up over boulders, yields a small squeeze to the left into phreatic passage. A 15m pitch is shortly encountered. Across the pitch a small window can be seen - not pushed.
At the base a dig through a window yielded another small aven with a tight muddy rift heading off, dropping 4m to a floor. (Not pushed, very tight and committing).
A trip in the summer of 2006 traversed across the top of the p35 for 22m to an alcove. Is this lead 7 below?

Leads
1) Small aven climb at base of the first pitch
2) Possible dig into chamber following water course in blind aven series
3) Bolt traverse in both directions may yield high level passage??
4) Tight rift in aven near muddy break down chamber
5) Tight drafting rift near muddy break down chamber. Needs hilting.
6) Route finding through breakdown may gain open passage.
7) Window across phreatic tube pitch, not pushed
8) Tight rift dropping 4m to floor not pushed.
