Granite pegmatite, probably a vein only a meter wide. Oak Hill is a relatively large geographic feature in Standish. In the 1880's, mineral collectors knew of a pegmatite vein which produced wonderful, mirror-faced columbite-(Fe) crystals. In 1886, Edward S. Dana, who was a summer resident in Southwest Harbor, Maine, when not at Yale University, New Haven, Connecticut, described the crystallography of the columbite-(Fe) from Standish. Unfortunately, over the decades, the locality's precise location has been forgotten and is now lost.
