2020 Update

 

This locality is on an undisclosed area of private land in the township of Gouverneur, St. Lawrence County, New York.  It was discovered by David LaLonde from Ogdensburg, New York, and in the summer of 2017 myself and Dave dug out the majority of the opening.  It was a huge gash vein in the Grenville marble measuring well over 5 meters in size and having numerous off-shoots to several meters in length.  Thousands of pounds of calcite and calcite crystals were extracted.  Very few were of collector-grade.  Probably the most noteworthy specimens were clusters of dolomite, though uncommon, were exceptionally fine.  An article on this location recently appeared in Rocks & Minerals magazine (March/April issue, vol. 95, no. 2., p. 168-72).

​

Several examples of the specimens from the occurrence are shown here.  None of the specimens from this location have been offered for sale on this website but I do have specimens available.  Please contact me directly if you wish to inquire about available specimens.
