Started in 1890 by John S. Lane Company mainly to provide railroad bedding, it was one of the first trap rock quarries not working talus. The company later established the still-operating quarry near Westfield, Massachusetts https://www.mindat.org/loc-3831.html (LeTourneau and Pagini, 2017). Now long abandoned, it is one of the few places in Connecticut trap rock where some anhydrite is still present in vesicles, the vast majority of it was dissolved away early in the paragenesis at almost every other trap rock locality.

Shannon (1920) describes this now little-known quarry:

Near the top of the lower flow there is much rock which has a deep maroon color and contains small cavities filled with calcite and deep-green diabantite [actually probably pumpellyite]. The secondary minerals of the trap are deposited in amygdaloidal cavities which may reach 20 centimeters in diameter and in veins up to 10cm wide which may persist for 20 meters. The most abundant mineral is colorless to pale yellow calcite, which forms groups showing varied crystal habits. The crystals reach 2-3cm in diameter; many of them are scalenohedral and display a number of forms. Quartz is common in druses of brilliant crystals lining cavities and coating other minerals, much of it being of a pale amethystine hue. Chalcedony and other forms of amorphous or cryptocrystalline silica occur lining geodes or filling veins solidly. Anhydrite occurs in large pearly masses showing cleavage surfaces often 10 cm or more broad. There is abundant evidence that anhydrite has been present in almost universal distribution, but it now remains undissolved only in the centers of the less pervious blocks of rock. Molds of anhydrite crystals varying from stout prisms to exceedingly thin sheets are abundant everywhere... Some of the veins and large amygdaloidal cavities are lined with fine little datolite crystals; these are to be described in the Proc. U. S. Nat. Museum.

Detailed Mineral List:

Anhydrite
Formula: CaSO4
Habit: Cleavable masses, molds surrounded by epimorphs
Colour: white to pale blue
Description: Extant crystals very rare in Conn. - nearly all were dissolved away and exist as platy to rectangular prismatic molds, but here there were "large pearly masses showing cleavage surfaces often 10 cm. or more broad. There is abundant evidence that anhydrite has been present in almost universal distribution, but it now remains undissolved only in the centers of the less pervious blocks of rock. Molds of anhydrite crystals varying from stout prisms to exceedingly thin sheets are abundant everywhere." Shannon (1920).
