Black Mountain quarry
The Black Mountain quarry is at the southwest foot of Black Mountain, three-quarters of a mile south-southeast of the village of West Dummerston, in Dummerston, and 5 miles north-northwest of Brattleboro. Operator, Presbrey-Leland Quarries (Inc.), 681 Fifth Avenue, New York.
The granite, of two sorts, chiefly "Dummerston white", is a quartz monzonite of very light gray shade, speckled with bronze-colored mica (muscovite and biotite), and of even-grained medium texture, with feldspars up to 0.3 inch and mica to 0.1 inch. Its constituents, in descending order of abundance, are clear to pale smoky quartz, showing effect of strain, with hairlike crystals of rutile and a few fluidal cavities in sheets; milk-white soda-lime feldspar (oligoclase to oligoclase-albite), some of it with flexed twinning planes, kaolinized and micacized; clear potash feldspar (microcline and othoclase) ; muscovite and less biotite, apparently intergrown and bent or twisted with fibrous muscovite stringers extending out from them into and between the other particles. Accessory: Apatite, rutile. Secondary: Kaolin, white micas, epidote, zoisite, calcite. There are crush borders about the quartz and feldspar particles.
The quarry, opened about 1877, was estimated in 1907 as measuring about 1,200 feet in a N. 20° W. direction along the base of the mountain, by 200 feet across and from 15 to 50 feet deep. It was reopened in 1921.
