Storia
In the Guia Monogràfica de Sant Llorenç del Munt, published by the Centre Excursionista de Terrassa in 1935, mention is made of the Avenc d'Alzina Teresa and it is given 12 metres of depth. We know that in 1964 members of the GES-CMB visited it a couple of times, correcting its depth to the real one. It seems that people from Terrassa confused it with another pit, also mentioned in the guide, as Avenc del Sot del Teix.
