This specimen consists of a rather flat, square-shaped piece of galena that acts as a matrix rock; one corner of the piece of galena is missing, and the resulting depression is partially lined with Anglesite crystals. These crystals occur as flat, tabular to prismatic crystals with rather steep, wedge-shaped terminations. Though many are incomplete due to growth against the host rock (part of which has been removed), there is very little evidence of human-induced damage. These crystals range in size from a few millimeters to nearly 0.5" (1.3 cm) in length, and in color from colorless to a moderately pale yellow. All have an adamantine luster and are transparent and very clear, though showing considerable internal fracturing. Trapped throughout the galena matrix are many other pieces of Anglesite, but all are broken, incomplete, and almost completely embedded. There is also a substantial amount of a yellow, powdery substance coating parts of the galena, which is likely a decomposition product.
