[1] Baltimore Gabbro Complex was an early roadbed material for the Central Maryland Region.
It was mined in the Stoney Forest area of Harford and Cecil Counties, along the Susquehanna in Baltimore and as far south as Laurel.
Barrick & Sons purchased the 600 acres chase property north of the historic town of Savage, Maryland.
The site is home to the Savage Stone quarry, mining Baltimore Gabbro for road bed construction.
The material is amble to support 50,000 pounds per square inch for road construction.
