Work at the quarry began in 1924.

The quarry is 1.5 miles (2.5 km) long, 0.5 miles (1 km) wide, and 400 feet (125 m) deep.

As part of the Chicago Deep Tunnel project, Thornton Quarry will serve as reservoirs to reduce the backflow of stormwater and sewage from Chicago area rivers into Lake Michigan. Thornton Transitional Reservoir contributes a 3.1 billion gallon capacity to the system, and is expected to contribute 7.9 billion gallons when the system is completed in 2014.
