A definitive account should be written for this hole.

Approached from the first hairpin, site 415 is approx. 90m away on 230°.

An excavated entrance which leads to a fine Yorkshire pot with good hangs for SRT. The first 11m drop is free climbable by jamming. This leads to a tight slot which opens out to the second 8.4m pitch. This ends on a pinnacle and a climb down through a rift to the head of the third, 7m pitch. The base of this is a level of some horizontal development at 245m altitude.

At Easter 2006 "rigged down 3 pitches and swung into bedding crawl. Rope for traverse was still hanging around  so went across the traverse  and up the rift beyond. Checked out the two inlets". The smaller one of these was pushed and dug until more rocks blocked the way.

Pitches of 13m, 8,4m and 18m follow in quick succession to a 5m free climb down to pools and an impenetrable slot.

Avens at the base of the 3rd pitch have not been climbed. A passage on the left at the 3rd pitch base meanders updip to a calcited choke. The down dip continuation across a rock bridge and is a body sized hole.

The "same pitch?" shown on the survey was investigated in 2003 and found to true. At Easter 2004, passages "found last year off the traverse" and 20m of new passage at the bottom were surveyed but not drawn up.

The cave is formed on one joint (130° - 310°) with an inlet entering down dip (15°) and has no connection with site 415.
