OUR EXPLORATIONS AT THE PIERRE-SAINT-MARTIN
16 years of expeditions already... (1997-2012)


 

In the past, we visited the Pierre-St-Martin area (French/Spanish Pyrenees) a few times, but only for "classic caving". In 1988 we did the through-trip of the famous Pierre-St-Martin Cave (SC3->Verna), and bottomed both the Lonné Peyret (-700m) and the Aphanicé (-500m) with it's magnificent 328m free-drop. In 1990 we bottomed the Couey Lotge (-600m), another splendid underground river. In 1997 we spend our first holiday with main goal "exploration". The Anialarra limestone plateau became our playground for the first, and certainly not the last time.

Limestone of Anialarra; at the background is the Pic d'AnieIn the remote Anialarra area, situated in Spain, some exploration waves had swept by in the past. The first one in the early '70ties, resulting in the discovery of the FR1/Gouffre Vaille-que-vaille (-337m), the FR3/Gouffre des Caou-Couges (-420m), the AN3/Pozo Estella (at that time -614m) and AN6/Pozo Frontenac (-406m). All this was a French/Spanish realisation, with a lot of heroism and tragedy, such as the death of young Francis Zamorra during a flood pulse in the pitches of Pozo Estella...
A second (and Belgian) wave followed in the '80ties, with the exploration of the AN51/Pozo de Acuarios (-390 m) that connected to the AN6, soon followed by the connection of AN6 with AN3/Pozo Estella, thus creating the "Anialarra Cave System", 711 m deep and 11 km long!
Despite some other explorations afterwards, one had to wait for a decade for another major discovery. It was again a Belgian club, SC Avalon, who found the the AN506/Pozo de los Ninos, -410m deep, in 1997 and 1998. This cave has got a gigantic pit, called "the Monster" 258m deep.

In 1999, another expedition resulted in the exploration of the AN519/Pozo Ibarra, -347m deep, with another big pit: the 222m deep "Extremist".  This cave became the fourth entrance of the Anialarra System and opens up great possibilities for re-exploring this system.   The 1999 expedition also found the AN534/Pozo del Eclipse, pushed to -130m and still going. 

AN51 -InletIn 2000 another big expedition was organized.  A big part of the cave system was resurveyed; and at a depth of -650 m, close to the end of the cave, a new part was discovered which  totals over 350 m of cave-passage.  In this part there is a realistic chance to get passed the terminus of the cave one day!

In 2001, we worked mainly in the upstream parts of the cave and made some very nice discoveries (Réseau des Affamées, an upstream rivier).

In 2002, a very important breakthrough was made in the upstream parts of the cave. A giant fossil gallery was explored over 650 m: Réseau Nostradamus

During the 2003 and 2004 expeditions we explored almost 3 km of new passages in that part of the cave.  The highlight is a giant gallery, over 600 m long and with a passage that is 50 m wide...!

The 2005 expedition finally delivered the downstream continuation of the cave.  We got through the terminal boulder choke, and explored a giant part with big rooms and very decorated fossil galleries.

The 2006 expedition became the icing on the cake. Three times we went to Anialarra, five weeks of caving fun in total. We re-discovered the river, explored many kilometres of magnificent galleries, found an important inlet that was explored over 750 m, and drastically changed the depth of the cave, for the very first time in more than 20 year!. The cave is now -731 m deep for a total length of 20,3 km.

In 2007, things were going well, we were pushing the river further and further, when suddenly disaster struck. Annette, one of the team leaders, got hit by a falling boulder and got severely injured. A 3-day rescue operation was necessary to get her out of the cave. But the expedition was not a failure, the cave grew to 21,3 km in length and -735,5 m in depth.

In 2008 all misery was soon forgotten, because this episode became one of the best ever. There was not only the come-back of Annette, but also the cave went on and on. The most downstream terminus (Trémie Crimson) could not be passed yet, but in the Tintin River we had fun for weeks. This river was explored further and further, during long, difficult and exposed trips. The Anialarra system grew 3 kilometers and now totals 24,3 km, for a depth of -739 m. We also made significant progress in other caves, e.g. in the AN60 where we finally arrived in a series of pitches, after having worked for many years in a very narrow meander.

In 2009 thing went very smoothly. Tintin River was pushed for several hundreds of meters in upstream direction up to a point where we are only 90 m away from another giant cave:  System Partages-Pierre-St-Martin (+80 km). A small dye-test soon showed us that the water of the Gouffre des Partages goes the Tintin River. In AN60 we reached -300m, the cave goes on. Another new cave was found, AN509-Pozo de la Mariposa, we reached -340 m and stopped (due to lack of time) above a big pit.

2010 was in all aspects an exceptional year. For the first time we went there in the winter, to search for "blowholes" in the snow. We found 65 of them! During the summer we checked them all. One of the caves that we found that way, was AN588-Pozo de la Grieta (-220 m). Other promising caves were found such as AN595-Gouffre Polaire (-175). In AN60 we passed last year's terminus and the cave was explored to a depth of -444 m, where it connected to the Anialarra System, to become a 5th entrance.

In the system we did some remarkable discoveries, such as the giant Blake & Mortimer room. The total length of the Anialarra System is now 27,5 km.  

In 2011 we made two important junctions. In august, we connected the Anialarra System with Gouffre des Caou Cougues (FR3): a 6th entrance, with two more "satellite" entrances, AN57 and AN548-FREU.

Only 3 weeks later, in september 2011, we connected Sima de la Mariposa (AN509) through a splendid 134 m pitch with the system. The total depth of the cave system is now -770 m, for a total length of 31 km.

2012 was the year in which we found a new cave, AN594 or Sima de la Verdad. We invested a lot of time in it because it could become a direct access to th most upstream parts of the Tintin River. By the end of the expedition, we were around -160 m and the cave is still going. We also explored quite some new pits and galeries in Mariposa and in the Anialarra cave system. The total length is now nearly 32 km.

The most spectacular discovery was made by our friends of MJC Rodez and GS Bilbao. In AN43, situated far downstream, they found the Anialarra river. Upstream they explored a giant gallery that nearly connected with Trémie Crimson, the end of the Anialarra System! Most probably the connection will be made in 2013.

 

The "Anialarra champion" !

Since a few years we award an expedition member with this trophy. We give it to somebody who has shown exceptional team-spirit and effort. 

This original trophy is made of a piece of limestone and a stack of totally worn pulleys of our Petzl descenders. In 1999 we started exploring the Pozo Ibarra with its 222 m pitch. After three weeks all of our descenders were worn to the bolt.

In 2012 Jack London (Casa/C7) was awarded this trophy. He can put it on a nice spot in the house, for a whole year!

Other people that received this trophy are:

  • 2011: Tobias Speelmans 'SC Avalon)
  • 2010: Friedemann Koch (SC Avalon)
  • 2008: Tjerk Dalhuisen (Speleo NL)
  • 2007: Rudi Bollaert (SC Avalon)
  • 2006: Bart Saey (SC Avalon)
  • 2005: Erik Van den Broeck (Hades)
  • 2004: Mark Michiels (SC Avalon)

  • 2002: Annette Van Houtte (SC Avalon)
  • 2001: Oswald Pauwels (SC33)
  • 2000: Tom Van Rooy (Technico)
  • 1999: Michaêla Van de casteele (SC Avalon)
