An unusual locality for gypsum! A cluster of amber gypsum crystals, mostly translucent, the largest of which is almost 11 cm long. Most of the crystals are terminated and show distinct 'duckbill' twins (imagine looking down a slightly open duck's bill...). Accented with a few patches of white, sugary gypsum. Strong fluorescence under shortwave UV; somewhat weaker under longwave UV. A few cleaved crystal edges are not a major distraction. Many fine display angles possible.
