Yelllow fibrous (?) radiating crystals of Betpakdalite-CaCa in groups to 2mm. The crystals are probably on the order of 0.2mm. I'm hesitant to call this Betpakdalite since it is not listed on Mindat for the locality. Given the crystals are fibrous-looking, it may be Chistyakovaite. It holds a Mineralogical Research Company label. Might be a sleeper.
