A village centered on the junction of State Routes 160 and 17 (coordinates are for there), it lies just north of an intensely quarried and prospected portion of the Middletown Pegmatite District located just east of Route 17 between Roaring Brook and the Glastonbury-Portland town line.
Roaring Brook was the site of felspar milling as described by Bastin (1910):
"John C. Wiarda feldspar mill. This mill, at South Glastonbury, is equipped with one chaser for crushing the feldspar and three small-sized tube mills. The capacity of the mill is said to be about 15 tons in twelve hours. A considerable amount of the material produced by this firm is used in glass manufacture and enamel ware.
"Howe mill. The Howe mill, at South Glastonbury, is operated during part of the year by water power of Roaring Brook and during the remainder of the year by steam power. Its capacity is said to average about 27 tons in twelve hours. The equipment includes 2 chaser mills and 5 tube mills, each 7 feet in diameter and 5 feet long."
From both mills the material was hauled 1 mile to the Connecticut River, then ferried across to Rocky Hill and shipped by rail.
