Barton Mine
Garnet (abrasives) mines operated by Barton Mines Company, LLC, were first on Gore Mountain (until 1983) and then Ruby Mountain, which is currently being mined. Henry Hudson Barton began mining almandine on Gore Mountain for use as abrasives in 1878. Tours of Pit #1 of the Gore Mountain mine are conducted for a fee, and some collecting is permitted.
Almandine on Gore Mountain occurs in both garnet amphibolite and olivine meta-gabbro. On Ruby Mountain, the rock is almandine-rich gabbroic anorthosite. Almandine crystals nearly 1 m in diameter have been reported here (Elements 9 (2013) p. 417). The almandine crystals can have some gemmy portions, but unfortunately, parting planes divide the crystals into thin (few mm) slices. Nevertheless, in 1969, then Governor of New York, Nelson Rockefeller, made the Barton garnet the New York State gemstone.
