A remarkable, large crystal of herderite from this classic locality. Herderite crystals of such size, from any US locality (or any locality ouside of Brazil for that matter) are extremely rare. This is a significant US species specimen, way beyond the norm of any reasonable expectation. Collected by Bob Whitmore in the early 1980s
