Other/historical names associated with this locality:
Nash and McCurdy quarry
The rock is typical muscovite-rich granite with a small amount of brown biotite and small pink garnets. On the northwest side of the quarry there are numerous muscoviterich bands and pegmatites within the granite. A large pegmatite at the north end of the pond has an irregular shape with many projecting tongues or fingers. The rock is highly fractured here and many of the horizontal joints contain yellow uranophane.
A pronounced flowage foliation strikes about N60°W and dips either north or south on the northwest side of the quarry, and strikes about N50°W and dips 35°NE on the east side of the quarry. Locally the foliation is erratic. Joints are not common but a small fault trending N40°W limits the north end of the quarry.
