Quarry Operations

Mining began in the San Gabriel Valley in the late 1800s - and at this site in Azusa in the 1920s.

Yet stone, sand and gravel have been mined around the world for thousands of years, as civilizations built entire cities with stone, sand and gravel.

Because of the strength of these aggregates, many of those ancient structures still exist today.
