In the end of the 1960s, during the construction of a water tunnel for the Siso Power Plant, a spectacular find of a 0,5 x 1m cavity lined with large yellowish green prehnite crystal was made by the workers. A total of under 20 specimens (to 12cm in width with up to 3 cm large crystals) is known and found their way into several collections.
