Quarries at the Keystone Arch Bridges Trail

One of several quarries on the trail and more as the railroad heads west in Becket, stone from these were drilled out and used to build the Keystone Arch Bridges. A quarry just before the 70 foot arch still has a feather drill in a boulder which cracked and was deemed useless. Drill holes can also be seen all along the cut area with its eye popping high walls.
