Construction of housing and fast-serve restaurants (Dunkin Donuts and Wendy's) in the 1990s and circa 2000-2002 on and just south of the former Hartford Drive-In site, SE of the intersection of state Routes 15 and 287, exposed the Holyoke Basalt with mineralized faults and gas vesicles. Assemblages dominated by abundant, colorful and well-formed calcite (which fluoresces yellow to white under LW, MW, and SW) with accessory quartz, prehnite, datolite, and minor sulfides formed over a 3-D network of tabular, dissolved anhydrite crystals make this locality particularly noteworthy. Also rare, for Conn., mordenite occurs here.
