Avenc d'Olèrdola

The first exploration took place in February 1951 by Francesc Español and Àngel Lagar during one of their outings for biospeleological purposes. Apparently, for years, the cavity had a second shaft in which it reached a depth of about 12 metres, but during the decade of the 1960s it was obstructed by a series of blocks thrown deliberately from the outside.

Speleologists from Vilafranca renamed it as avenc del Conill and in Vilanova it was known as avenc del Castell, but in both cases after the second shaft was plugged.

We update the record (March 2016) including the topography, until now unpublished, made by Oleguer Escolà at the end of 1963 when the second small shaft still existed and reached 8 metres deep and not 12 as had been said.

Locality of Troglocharinus variabilis olerdolai, captured by Español and Lagar on 11-2-1951. (Initially it was named Troglocharinus españoli olerdolai; and possibly it will change again, if it has not already done so).
