A "common" granite pegmatite that crops out at the intersection of Dripps Road and Saybrook Road (Rt 154) in southern Middletown. According to Behnke et al (1993):

"In September of 1991 an important new locality for well-crystallized garnets was discovered in Middletown, Connecticut. Well-formed trapezohedral crystals up to 7 cm in diameter were found in a simple pegmatite which was remarkably devoid of any other accessory minerals. The nearly black garnet crystals, which occur in groups up to 30 cm across, are among, the best ever found in Connecticut....The garnets occur in pods and are embedded in the microcline, quartz and minor muscovite of the pegmatite. By carefully working individual pieces of the pegmatite, sometimes for days, remarkable specimens have been revealed."

The pegmatite was blasted again circa 2007 to widen the road to the construction company behind it, which turned up some more almandine crystals.
