Originally labeled as Quartz ps after Laumontite, but looks more like a pseudomorph (or epimorph) after Anhydrite. The centers of the crystals are hollowed out. Any which way, it a nice example of replacement.

I'm not sure if these crystals are a replacement of something thin and tabular or just a freak of nature. These are creamy brown tabular crystals of Quartz to 4cm. The locality needs work.
