This site is in the bottom of a gully, just outside a field, and has a very cold draught coming out of holes in boulders. There is evidence of an intermittent stream in the channel below - it looks like a flood overflow.
After a good poke around in boulders, an entry was made about 3-4 m above the lowest point at which any water might resurge. A very low gap back to the right (facing up gully) is visible. This gave the impression that the water comes from higher up the gully, running under boulders at low level. Worth checking in a flood.
Other holes have been opened up slightly higher in the gully. The top hole seems most promising, but requires some engineering work to get further down amongst boulders. The draught here is very strong even on a cool day outside.
Over Easter 2009, there were several visits, engineering works commenced. In the promising top hole a shaft was sunk for about 5m to a point where we felt we had reached bottom.
The draught seems to be coming from the right part way up the hole under a large boulder. An attempt has been made to get down the back of this boulder and that may still be the way to go. A small flood pulse come through at one point and the dry channel start to run. There was not a lot of water on this occasion, but the draught and general location still make this a worthwhile dig.
