Caratteristiche

Località

By the track that leads from Mieres towards Sant Aniol de Finestres, once past the Iberian settlement of la Palomera and before reaching the coll de la Palomera, we will turn right onto a faint track as far as a high-voltage pylon, and continue straight on along a path until we reach some flat slabs where the entrance of the pit is located. The place is known as la Tuna and appears marked on the ICGC map. Tuna is a very common geotope throughout the area and is synonymous with fissure. Approximate coordinates, without much precision.

Storia

At the beginning of 1957 four members of the Centre Excursionista de Banyoles, J. Cortada, J. Cruells, I. Palmada (son) and J. Tarafa, accompanied by a person from Mas Sec and equipped with helmets, lamps and a rope ladder, explored at the Roca del Migdia in Mieres a pit which they calculated to be about twenty metres deep. In the magazine Cordada no. 25 (1957) a brief notice of this exploration also appears.

On 30-4-1997 members of the Centre Excursionista d'Olot explored the cavity, thinking it was an unpublished cavity, which they named Avenc de la Vaca.
