This specimen began as a cluster of gypsum crystals up to almost 3 cm wide, which become covered with a think black goethite crust. Later the gypsum dissolved away leaving their imprints in the goethite. Hence, this is an epimorph. Often stated to be an 'epimorph after selenite' ('selenite' should **only** be applied to transparent gypsum), but because we cannot determine if the gypsum was transparent, we cannot say the gypsum was selenite. A classic for the locality, which sits perfectly for display at numerous angles not needing a stand.
