A one-time find during housing construction (2005) and adjacent High Street interchange with Interstate 95 reconstruction. The rock ledge at the site is the Jurassic Talcott Basalt. Mineralogy is similar to that of other nearby areas such as the Cinque Quarry and McLay Avenue.

This place may be equivalent to that noted by Schooner (1961) from at that time "recent" blasting along the then newly constructed Interstate 95. He describes quartz, calcite and goethite crystals very similar to those found around 10 years later at the Cinque Quarry. Old specimens just described as from "East Haven" or from "Mullen Hill" may in fact be from the initial blasting, which cut through a hill in the Talcott Basalt.
