Part of a crust of intergrown Halite crystals makes up this cabinet specimen. These crystals are generally in very good condition and measure up to 1.1" (2.8 cm) along an edge. Their cubic form is excellent, and all show the hopper effect that occurs when the edges of a crystal grow more quickly than the centers of its faces. The halite has a pink color and a pearly luster, and is dimly transparent in some areas. Most of the larger crystals are covered with a very thin crust of thenardite, a sodium sulfate mineral that likely pseudomorphed from the Halite. Otherwise, there is no other material present.
