Description
Morphology
An old sparry calcite quarry, with a 4x4 entrance and a 2-metre shaft with a sloping floor; at the end of this, a small opening on a steep ramp communicates laterally with the dome of a 5-metre shaft.
Speleothems
In the 5-metre shaft there is a formation partition that divides the shaft in its central part.
History
This cavity was discovered as a result of the working of the sparry calcite quarry, the date of which we do not know.
The ERE of the CEC explored and surveyed it on 6 November 1964, naming it Avenc de les Brosses nº 1, together with another very nearby pit which they named Avenc de les Brosses nº 2. Both cavities remained unpublished and the respective surveys remained forgotten in the archives of the ERE of the CEC; only Jordi Lloret, in his Catálogo Espeleológico del Pla d'Ardenya (1979), mentions the avenc de les Brosses, but he does not publish the surveys.
In 1996 the SEO-CE Vallirana rediscovered them and renamed them Avenc del Molí in the case of the avenc de les Brosses nº 1 and avenc SM-23 in the case of the Avenc de les Brosses nº 2.
