A climb down in the small shakehole soon leads to a tight pitch. At the bottom the passage passes beneath the aven where Wade's Entrance joins, and after a further it goes round a series of bends to where the last pitch of OBJ Hole enters. There is a chamber after a further where a small stream enters from an inlet passage. Downstream a succession of climbs and a pitch reach the main pitch of . South-East Passage in Gaping Gill may be stepped into at the level, but the shaft continues in two stages as South-East Pot to a deep pool. This is a window into a large underwater passage, and dye tests have shown that the water from Gaping Gill Main Chamber and from Stream Passage Pot flow through this passage. Above the final shaft there is a tight passage, Horrocks-Stearn Crawl, which connects to Bar Pot above its main pitch.
