Scores of tetragonal tabular Wulfenite crystals rest on the goethite/limonite matrix of this specimen. Most of these are tiny, not measuring more than 1 or 2 mm in any dimension, but many are much larger, achieving dimensions of up to 0.4 x 0.3 x 0.1" (1.0 x 0.8 x 0.2 cm). Several of the larger blades are noticeably damaged, but most are intact and show excellent form, with clean faces and sharp edges. They have an orange color that deepens as their size increases and show a bright, adamantine luster. All are at least translucent, but the many tiny crystals are actually transparent and appear to be nearly colorless. Close examination of the host rock reveals a warped but noticeable crystalline form. It is actually composed of a calcareous mineral (likely calcite) that is stained brown from limonite.
