Eastern slope of Pico Samelar, near the summ


A cicular entrance shaft of 4m diameter immediately onto P30


Circular entrance (4m diameter) leads immediatley on to P30 that is blind.  Half way down the P30 is a pendulum to a P68, which is quite spacious.
The P68 leads to a a series of ramps and pitches (P11, P10, P10, P10, P30) that spiral down to -178m. An up pitch of 15m leads to a down pitch of 15m?
This leads to a series of tight meanders, that must be negotiated by climbing up and down, until a ramp of 8m into a boulder choke is found.  This is followed by a pitch of 12m, on one side is a narrow pitch to a meander. (approx. -190m)
A C7 and P6 at the bottom of which is a loose steep ramp to a small pool of 5m.  A small chamber leads to another meander that becomes too tight at -224.8m
