Approach

64m below and 100m from the Pico Boro, in a gulley that runs down from the peak of a bearing og 60 degrees

Entrance

a 4m by 0.5m rift underneath the largest boulder in the gulley

Description

A 24m entrance pitch with bolt rebelay under jammed boulders one third of the way down, lands in a chamber with two inlets.  These are climable for 6-8 meters.  The only exit is a 25cm slot in one wall which is the top of the second pitch of 8m.  At the bottom a climb over a 1m wall leads to the third pitch of 39m, in a 2m wide rift.  6m down a jammed boulder is passed.  A 9m pitch into the terminal chamber follows immediately.  The passagea taking water out of this chamber is too tight to negotiate, and a wider fit enterd by a 4m climb over the top, also close down At the level of the jammed bouler on the third pitch, it is possible to pendulum onto a rock bridge and rehang the rope on the far side.  Another 10m down, a second pedulum onto a ledge leads to a hole at the ened of the rift.  This is the the top of a 28m pitch into the final chamber.    There are no other possible high level routes
 
Alternative route:
A 25m entrance pitch lands beside an ice cone. Away from the ice cone a slot over a large boulder provides the way on. A drop of 11m, leads to the third pitch of 10m, immediately followed by a 30m pitch landing on a boulder floor. The water sinks here, and reappears at the next pitch of 11m which follows shortly. At the base of this pitch is a narrow meander, which becomes too tight but has a draught at stream level.
