The ground this borough actually sits on
This is Lehigh Valley country: 11.3 miles from Bethlehem and 14.6 from Easton, on the shoulder between the Bucks County quarries and the industrial river towns.
The stone is close. The Blooming Glen Quarry lies about 8.0 miles south-east with ten people on the books, Naceville Materials about 8.7 miles south at Telford with 14, and H & K Materials about 11.5 miles south-east at Chalfont with 13.
North it is intermodal and rail instead — the Bethlehem ramp about 9.1 miles, the Bethlehem intermodal yard about 9.2, Florence Yard about 9.5 and East Penn Yard at Allentown about 10.9.
Further out, the same stone under other names
Those are not the only pits within an hour. Perkiomenville Quarry lies about 13.1 miles south-west at Green Lane with 17 people, Plumstead Materials about 13.1 miles south-east at Doylestown with 13, and Harleysville Materials about 13.5 miles south with six.
Eureka Stone Quarry sits about 15.1 miles south-east at Chalfont with eight.
Short repeated hauls into a metropolitan market wear a truck by duty cycle rather than by distance, so brakes, clutch, suspension and tyres go before the engine does.
