Explore world-renowned geology and mineralogy in Western Maine!


Oxford County Maine is truly unique in its pegmatite formations, incredible variety of precious and semi-precious minerals. Our area has a centuries-long history as a prized mineral source for industrial applications, collectors, and academics.
Guided tours of actual mine excavations!
-- Tours run May-September, subject to weather

Enter a ledge cut first mined over 80 years ago. See the geology and mineralogy in some of the oldest and most famous mineral mines in the greater Northeast Region. Then, step into the cool interior of the two tunnels that dramatically present the local mineralogy and mining techniques of days gone by.
(No digging will be permitted in the tunnels, for safety reasons).
