Augelite

The matrix of this specimen shows a surface encrusted with augelite, an uncommon aluminum phosphate mineralization. These green-yellow crystals have a preferential coating of what appears to be a micro siderite drusy

Rapid Creek, along with several other localities in the Yukon mining district, is located in an extremely remote area, accessible for only a few months in the summer due to the harsh winter weather, when the region is buried under snow and ice. Collecting in this area is particularly challenging, as it is known for being one of the most treacherous terrains in the world for specimen collecting. In addition to the rugged landscape, collectors must contend with swarms of mosquitoes and black flies, adding to the already formidable conditions. Initially, it was the blue lazurite that had attracted the attention of mineralogists, collectors, and dealers, leading to the discovery of over 70 known minerals in the region, including eight type localities.
