Geocache Description:

This earthcache will show you an old thulite quarry. You will see the quarry spred out over a small area. Today there are almost no activity here but earlier stones from this quarry were shipped all over Europe. You will see that the bedrock is pink/red where the quarry is.

Thulite (sometimes called rosaline) is an opaque, massive pink manganese rich variety of the mineral zoisite. Thulite is often mottled with white calcite and occurs as veins and fracture fillings transecting many types of rock. In mineralogical literature, thulite may sometimes refer to any pink zoisite.

Thulite was first discovered in Lom, Norway in 1820. It is named after the mythical island of Thule in the belief that the island is Norway. Thulite is used as a gemstone and carving material in the manufacture of jewellery and ornamental objects.

Thulite is also found in the Austrian Tyrol, in Mitchell County, North Carolina, and in Western Australia. A new, more recent find of high quality thulite was discovered near Riverside in Okanogan County, Washington, USA.
