Description 1



Overflow stream sink in dry valley. A series of small pitches brings you down to a chamber where the streamway is met. Upstream is a strongly drafting, small, wet hole (unexplored). Downstream begins as a crawl followed by a stooping traverse which enlarges to walking passage. Further on the streamway degenerates to a small and tight rift where a climb up bypasses a sump. Here a rat's nest was spotted. Beyond the cave regains more sizable proportions, continuing as walking and a series of climbs until a final 50 meters of narrow, tortuous, gravel floored canyon which ends with the stream sinking in the inevitable gravel choke. Many avens were noted entering on the western side. There are also several unpushed climbs.
