Mount Grace, 1,617 feet (493 m), is a prominent monadnock.
Emerson (1895) describes the locality: "High up on Mount Grace in hornblende schist the mineral [tourmaline] occurs abundantly in radiating groups about an inch across of shining black striated needles. It occurs also diverging in both directions from a plane which is only marked by a line of fine black grains and from which the needles go out at right angles. The tourmalines have often absorbed all the iron from the surrounding rock, and a fine granular quartzite slightly tinted by epidote remains.
