Avenc-balma del Serrat de les Esposes

Known since time immemorial by the people of the area and later by hikers and climbers. Despite this it had never been cited by speleologists. Although in the Catàleg Espeleològic de Catalunya. Vol 3 - Cerdanya (Jordi de Valles, 2009) it is cited with practically no data and from a list of cavities by Gener Aymamí (2004), the Balma de l'Avenc, which seems fairly obvious that it is the Avenc-Balma del Serrat de les Esposes and, the nearby Balma del Pla de les Esposes, of which it only says that it had been a sheepfold for livestock. We think that very possibly it is the one known as Balma de Segalars.
