The Aegerine appears as balls of green needles in the center. They are perched on an base of microcline crystals resembling white plates. To the right is a rose colored eudialyte. There is also a clear crystal which I think is natrolite, but am not certain at this point. |

This is a very typical example of a large contact zone cavity at STA. Quarrying operations generally avoid this material. But sometimes it can be found by the cubic meter. Unfortunately the analcime is not very attractive in person and there are few other minerals. Smaller cavities are more interesting - they can ... |
