Fletcher Pegmatite

A former open pit mica and feldspar mine.

Mineralization is granite pegmatite, Grafton field. Located near the village of North Groton. (Has produced remarkable examples of hydroxylherderite, strengite, phosphosiderite, strunzite and other pegmatite phosphates.)

Local rocks include rocks of the Littleton Formation, Upper unnamed member.

PLEASE TAKE NOTICE: The Fletcher Mine has been closed to the public since the 1970s. The property is posted against tresspassers. Prosecution will be the result of trespassing. Adjoining property with mines is also privately owned. Please respect wishes of property owners concerned with your safety in mind.
