Long-form identifier:

mindat:1:2:3782:5

GUID (UUID V4):

Oxford pegmatite field.
Granite pegmatite.
Local rocks include Carboniferous alkali feldspar granite (muscovite accessory mineral).

A former rare mineral specimen quarry. Briefly worked in episodes in the mid-20th century for feldspar.

Originally a mineral collector's site in the late 1870s. Opened by Nathan Perry and Edgar D. Andrews in the early 1880s. Originally called Harndon Hill, the name changed in a complex change of names about 1917. Operated solely by Nathan Perry by 1882. Operated for massive topaz for educational mineral collections in the 1970s by Col. Joseph Pollack of Harrison, Maine.

The locality is the type locality for hamlinite, now regarded as a synonym for goyazite.
