Quartz is common as small colorless crystals in most cavities with microcline. Larger crystals are often smoky. At this locality, the smoky quartz is unusual in the fact that what appears to be a typical smoky colored crystal will appear amethystine when light is passed through it. Titanite forms tiny crystals, most 1-2 mm long. It is common in some boulders, but is generally uncommon.
Zircon is common in many areas.
Most crystals are small, up to about 4 mm long, but larger crystals have been found. They are brown, greenish brown or rarely orange in color. Location map of the Washington Pass area showing some of the collecting areas.
