Selleck Road, West Pierrepont, NY

Occupying an east-west ridge just south and parallel to Selleck Road in West Pierrepont this location has been collected for decades.   The main part of the ridge is on state land and accessible without much walking, thereby adding to the popularity of the site.  Tremolite is everywhere, tourmaline (v. uvite) is much more localized along the ridge.  Both the light green tremolite and the uvite is typically etched and non-gemmy, however isolated pockets of very gemmy material has been found.
