Come join us on this very rare tour. Thornton
Quarry is one of the largest aggregate quarries in
the world. The quarry is 1.5 miles long, 0.5 miles
wide, and 450 feet deep at its deepest point. The
Quarry is so vast that the entire village of
Thornton could sit comfortably on its floor. Lunch
on your own follows at the Quarry Restaurant.
