There is no actual mine at Mine Ledge, which consists of a large quartz outcropping in the southwestern part of the town.
Hitchcock (1877, p. 508) describes the locality and the origin of the name: "Just to the north of the road that passes through Mine Ledge, in the quartz we find a quantity of iron ore, chiefly limonite, that forms botryoidal and mammillary masses on the quartz. From this circumstance this quartz hill received the name it bears, though the ore is not found in workable quantities."
