Known for a remarkable occurrence of well developed Triphylite crystals up to 15cm length enclosed in Feldspar. Forms an elongate body 180 m long and between 1030 m wide, which bulges on the northern side. It terminates abruptly and reappears a little further along strike and continues as a much narrower body for another 70 m.
