A difficult subject to photo since there is such depth of field. The micro crystals number in the thousands, The yellowish crystals in the photos are mostly Leucophosphite but some are Jahnsites. They are all about the same size, which is tiny....about 0.3mm. Some are striated, and these are Jahnsite crystals. The remainder is acicular Rockbridgeite. There is also secondary green and formless Leucophosphite, which is a replacement of Triphylite.
