Pretty much the premier US locality for great crystals of this typically rock-forming amphibole, this piece features a terminated, undamaged Arfvedsonite that rises 20 mm above the microcline and passes through to the other side of the piece. The primary 3.5 cm microcline is doubly terminated and nearly complete, the other two are terminatd but have some contacts. A great piece overall that measures 3.5 x 4 x 5.5 cm.
