A stalactitic crystal of fibrous, pearlescent, and translucent, snow-white ulexite, measuring 9 cm in length, is festooned with lustrous and translucent, white crystals of colemanite, to 1 cm in length. Unusual! I have not seen this association before. It comes with a label indicating it was collected by Jim Minette, here, in 1980.
