Other/historical names associated with this locality:
Bull Run Stone Co. Crushed Stone Quarry, Bull Run Stone Co.
Located near Conklin.
Known for exceptional apophyllite-(KOH) crystals. Meier and Kearns (2011) determined much if not all of the northern Virginia are uniformly near end-member apophyllite-(KOH) and verified its occurrence at this locality. (Lance Kearns, personal communication, 2011).
