“This is a micromount specimen of phillipsite and iridescent calcite from Blair County, Pennsylvania. I acquired the specimen from Don Smoley. According to Mark Heintzelman (2004), this locality was temporarily exposed in a shale pit along West Loop Road outside of Hollidaysburg in Frankstown Township. The site was active in the 1980s, but is now closed. Jamison K. Brizendine specimen and photo References Cited: Heintzelman, M.R. (2004) Phillipsite.
