An UNCOMMON and very showy combination specimen from the East Colusa Mine at Butte. Baryte is a widespread, but uncommon gangue mineral at Butte. This excellent and nearly undamaged piece features a "mountain range" of jagged, tabular, translucent and pearlescent baryte crystals jutting upward from matrix covered by needle quartz. The baryte is flanked on both sides by lustrous, olive-green sphalerite crystals, another uncommon occurrence with baryte at Butte. Classic, old-time, uncommon and desirable Butte material from the John Ydren Collection.
