The cave is located in a small shakehole, the entrance partially obstructed with logs.

Description: A 25m pitch drops to a chamber, containing more logs and yak bones. [Some potential ways down through the boulder floor of this chamber have not been dug.] [Looking down the cave, a short climb down on the right hand wall has not been investigated.] The way on is through either of two windows (the higher of the two is slightly larger and easier). Beyond the windows, [a climb up has not been investigated;] the way on is down a 6m climb, slightly constricted at the bottom, which leads to a second chamber. [A muddy climb up on the right hand wall of this second chamber leads to a rift which closes down almost immediately.] A 5m climb up on the left (handline useful) leads to a rift passage which at one point widens to become a small chamber. Following the rift beyond this chamber gains the head of a 15m pitch. [5m above the bottom of the pitch, it is possible to leave the rope and proceed in either of two directions: to the southwest, it is possible to reach the base of an aven, which is at least 10m high; to the southeast, a rift is gained, and closes down after 5m.] At the bottom of the pitch, the base of the southeast-heading rift has been dug out for 5m, and leads to a body-sized vertical tube that heads downwards for 2m. At the bottom of the tube, space beneath a low undercut can be felt with the feet, but has not been pushed further.
