Thumbnail Specimen, housed in acrylic museum display box. Uralite is a colloquial term for actinolite pseudomorphing diopside. The steep mountain road to Calumet was bad years ago when I visiting. Upon a recent visit it was impassable. This is skarn deposit where the crystals are covered with calcite. The calcite must be removed to expose the epidote crystals underneath. Skarn is an ancient Swedish mining term.
