Thomsonite is one of the less common members of the zeolite family. In this case, it has grown as a large, ivory-colored crystal aggregate, measuring 6.5 cm across. It has formed on an earlier generation of green, prehnite, to 1.5 cm across. The rarity and size of the thomsonite, make this a very collectible specimen NOT JUST for the locality but rather significant for the species as well.
