The obvious pit by the "high level" route to 161 was descended using IRT (indestructible rope technique) after declining to use a Bunda belay. Ended at about -12m (choked as usual) with a ledge about halfway down.
The cave lies right beside the old high-level path to 161 (on the right as you head up to 161), on a section where you're walking over soil-like stuff between bunde bushes. It's just near the ankle-breaking hole.
