Other/historical names associated with this locality:
Beryl Mountain pegmatites; Beryl Hill; William's ledge
Granite pegmatite, Alstead field. Local rocks include Ammonoosuc Volcanics, bimodal volcanic rocks.
A granite pegmatite-beryl/Be-feldspar-quartz occurrence/mine located near the village of South Acworth, on private land. Owned by Sadie Cohen (1954).
Beryl Mountain was known in the 1820s and a famous expedition went there in 1829, led by the young Charles Upham Shepard, with Edward Hitchcock and others. By 1837, Francis Alger, noted amateur mineralogist and editor of Phillips' Elementary Treatise on Mineralogy (4th edition, 1844), had found giant beryl crystals (to 4 feet by 5 inches across one prism face = 1.22 m x 12.5 cm) and at that time were regarded as world record size. The longest reliably reported beryl from this locality is 5 feet (Cameron et al., 1954), although some reports of larger crystals (to 6 x 1 feet = 2 x 0.3 meters) appear unsubstantiated.
The most interesting locality to the mineralogist, is 'William's Ledge' or 'Beryl Hill,' celebrated for the immense size of its beryls which have been sold to cabinets, in various parts of the world....There is one of them in the Imperial cabinet - in Vienna, highly prized even in that superb collection. The Acworth beryls, when perfect, have a fine light blue green color, of that variety known as aqua marine [sic].
Many large crystals have been saved from this mine in museums. The amount of beryl mined from here has been vastly under-reported because of Cold War secrecy. Anecdotal reports suggest that the pegmatite as a whole contained 20% beryl!
