As an article on the classic danburite locality near Russell, New York, was going to press (Chamberlain, Lupulescu, Bailey 2015), another danburite occurrence was discovered farther to the west, in the Town of Macomb. This locality has similar mineralogy but a very different geological origin than the Russell occurrence. The purpose of this brief article is to report this second occurrence of danburite in St. Lawrence County, New York.
The new danburite occurrence is less than 100 meters west of Locality 28 described in Brown (1983) on the old Downing farm north of Pierces Corners in the Town of Macomb, St. Lawrence County, New York. The property is privately owned, and permission of the current landowner is required for access.
