Geocache Description:


The area of the Mont-Perdu is registered since 1997 on the world inheritance of UNESCO.

On the french side, the circuses of Gavarnie, Estaubé and Troumouse offer particular aspects of this site of high mountain.
On the spanish side, in the province of Aragon, the canyons of Ordesa, Niscle and Pinete are among the deepest of Europe.

This earthcache offers the possibility of an excursion to the breach of Tuquerouye in order to admire since a single view-point the Frozen Lake, the northern face of the Mont-Perdu, its suspended glacier and its unstable seracs.

During your walk, you'll be able to discover these wild landscapes resulting from the double action of the erosion and the plate tectonics. You'll also be able to measure the impact of the reheating of the planet by seeing the retreat of the glacier of the Mont-Perdu.

The terrain park owes its originality to the predominance of limestone : the massif of the Three Sisters is the largest limestone massif of Europe. These sedimentary rocks accumulated below the sea in the primary era (mainly limestone, but also marl and sandstone) were at the beginning of the Tertiary era raised, folded and deported.

In the quaternary era, glacial erosion carved limestone rocks. They gave the landscape this aspect very assertive of circuses and glacial valleys into U form, as it can be seen in the valleys of Ordesa or Pinède. The karstic transformation came in addition to glacial erosion, creating multiple caves, avens, gorges, combs, sinkholes, and so on. Thus, in the canyon Niscle and garganta of Escuain, the upper part is an icy circus while the lower part is between deep gorges.

This cache being an earthcache, to be able to log a "found it", you'll be required 2 things :
- take a picture of yourself on the breach, at the given coordinates, beside the refuge, with the glacier of the Mont-Perdu in the background and your GPS in hand.
- send me by email before your log the answer to the following question: "What is the name of the 'Three Sisters' ?"

Good luck !
