Avenc del Torrent del Coll de la Creu

Explored in the middle of the 90s of the last century by Toni Asensio and Pedro Valdepeñas, at that time belonging to the CE Vallirana. Shortly afterwards, at the end of the same decade, it was explored by the Espeleo Grup de l'Hospitalet de Llobregat; they named it with the initials H-6, and with the name avenc del Fondo. This meant that it appeared published both in the catàleg Espeleològic del Massís de l'Ordal and in the Catàleg Espeleològic de Catalunya (vol.6), as if they were two different cavities, when in reality it was the same cavity.
