Unlike many St. Lawrence County locations, the Owen Prospect off Irish Settlement Road in Pierrepont is a newly discovered site. But like many others, the mineralization here is scattered and geologically diverse. Exposed outcrops of marble are cut by silicate bearing assemblages. As the silicates are a bit “softer” it appears that the best collecting process may involve finding some loose weathered out mineralization in the dirt and digging down to bedrock. The few locations that have yielded nice specimens to date do not appear to have been found from outcrop.
September 14, 2013: I met up with the St. Lawrence Mineral Club and the SUNY-Plattsburgh Geology Club for an interesting visit to Benson Mines in Star Lake, NY. Approximately 12 members of the St. Lawrence Club and 15 undergraduates from Plattsburgh were guided through the property by the current caretaker of the property, George Peerson.
Benson Mines was an open pit iron mine that exploited a magnetite-martite rich unit in the high-grade metamorphic terrain of the Appalachian Lowlands. The pit is not a beautiful tree-lined lake just north of the town of Star Lake on Route 3.
New York is rich in mineral collecting sites. Many have been known for hundreds of years, but others are being found every year.
The purpose of this site is to capture personal knowledge of sites I have visited, and others that I would like to visit. This input includes maps, field pictures, mineral photos, and literature references. It is not meant to be complete in any category, and I intend to continually add to the site as I explore New York geology and minerals.
