Mt. Tom Quarry
A trap rock quarry in the Jurassic Holyoke Basalt. The quarry closed in 2012, leaving rock walls about 200 feet high. The property owners at the time Mt. Tom Companies Inc. planned on filling the quarry pit with soils unearthed during regional construction projects.
In 2022, the Massachusetts Department of Conservation and Recreation purchased the quarry and adjacent former ski area for a total of $900,001. The state will keep the site as-is, block vehicles from entering the quarry, and add a guardrail around the quarry to protect guests from falling in. The aim of the purchase was to prevent the site from becoming a clean-fill operation.
The quarry is now (2024) part of the Mount Tom State Reservation.
