The top of this specimen has lots of poorly formed mckelveyite crystals scattered about with a couple of nice ones, especially the biggest. As well, there are several nice yellow thomasclarkite crystals, the large of which were contacted smoothly by an unknown crystal, probably microcline. One of the crystals is perfect. Rare Yttrium-rich minerals!
