The Montmorillonite in this specimen exists mostly as fibers included in a partly-cut piece of quartz. They are in excellent condition, being protected through inclusion, and reach lengths of about 0.9" (2.3 cm). Though they are difficult to study, they may have some appreciable monoclinic form. Like other specimens from this locality, this material has a pale pink color and likely a dull luster, and is translucent to opaque. A large flat face has been cut into the quartz so that one can easily see it, and part of a natural crystal faces serves as a base.
