Founded in 1976, Endless Mountain Stone of Susquehanna, PA, was one of the pioneers of bringing automation to Bluestone, and it also firmly connected to the industry’s past with the acquisition of a quarry site that dates to the 1840s.

The company was established in Northeastern Pennsylvania by Robert Coleman, and the operation is currently run by his son, Butch. “My father had a background in the building stone business in the Poconos [of Pennsylvania], and he decided to move here and open a quarry,” Butch Coleman explained. “We kept growing, and in 1987, we brought the first automated bridge saw for stone into Pennsylvania.”
