Cueva del Mazarrasa

Alternate Names: T87, Cueva de Mazarrasa, Torca del Mazarrasa, Remon


CO-ORDINATES: 30 T X:0360912 Y:4785988
LENGTH: 1720m (including mine)
DEPTH: -318m


Obvious mine entrance at the side of Caseton de Andara (White House).  The entrance is completely collapsed and access is not possible.  There are probably other ways into the system, from higher mine entrance, but no connections have been made as of 2017.  Suerte (T88) and General (T89) are the most likely entrances, but both have collapses and should be explored cautiously.



Stooping mine entrance

This is a really sporting trip with lots of long pitches.

A stooping mine entrance leads to a dam. Continuing on, through knee deep water, a natural shaft is reached. This is the head of a 55m pitch. Bolts in the wall give a good free hang all the way to the bottom, where a boulder slope is reached. A 9m pitch follows.

From the bottom a loose boulder slope leads to the head of a 15m pitch. Below, another boulder slope, followed by a 3m climb, leads to a 45m pitch, Pendulum Pot. It is possible to pendulum into an obvious side passage 10m from the bottom of the pitch.

A 13m pitch, follows shortly and at its bottom a short traverse leads to a large hole in the floor. A 4m pitch, followed by a short climb returns you to the big shaft which is 29m deep.

From the large chamber at the bottom the way on is down a 3m climb and along a tight rift.  A crawl leads to a 24m pitch and large boulder chamber. Continue down the boulder slope until the far wall is reached.  After a slide and climb down between the wall and boulders the passage continues to a series of short climbs.  Next follows a series of sporting pitches in easy going passage.

Eventually the rift narrows and the going becomes more difficult.  After a small chamber the way on is either at floor level, which is tight and strenuous, or a traverse along in wider passage, followed by a 9m pitch to floor level.

A 6m pitch is reached which drops into a small chamber. The going becomes easy again but only for a short distance, before the rift becomes very tight.
It can be followed for another 100m, past a small inlet to a sump.

No ways on were found
