The Astro Mine was discovered in the Sentinel Rock and Specimen Rock area of the Pikes Peak batholith by Kyle Warrington (Sacred Geology), former Delaware resident and then a Colorado transplant. It consists of two pockets: Astro Pocket No. 1 and Astro Pocket No. 2. They were all named in honor of his golden retriever, Astro, who passed away.
It produced smoky quartz, but it is best known for its cubic fluorite that is mostly colorless but purple on the four corners of the cube. Many of the purple corners are overgrown by a later transparent layer of colorless fluorite, which gives the purple a floating appearance. The fluorite is also occasionally green.
