A botryoidal Wavellite crust coats a portion of the pale gray host rock of this hand specimen. The crust is made up of intergrown Wavellite clusters that reach diameters of 0.7" (1.8 cm) and are generally in good condition. Each cluster is made up of heavily intergrown, radiating crystals whose slender orthorhombic bladed forms are almost impossible to study. A few of the clusters have been broken, revealing the radial nature of the crystals, and showing a dull pearly luster. Intact clusters have a moderately dark green coloration, though their interiors tend to have a much paler color. Some of the smaller clusters are translucent, but the largest ones are essentially opaque. The host rock on which they rest appears to be made of shale or a weathered slate, and a few other small or partial Wavellite clusters are scattered on it or wedged in cracks.
