A slate quarry in a town named for the trade
The operation here is Manhattan Quarry - Penn Slate, a surface working in dimension slate under Penn Slate, Inc, carried at Mine Safety and Health Administration as identifier 3600207 with four people on the books.
The town took its name from the industry, the way Granite in Oklahoma and Stone City in Iowa did.
That commodity travels differently from stone
Those four people are not producing aggregate. Slate ships as palletised roofing and as dimension slate on flatbed — a light and fragile load next to granite or limestone block, which changes the truck rather than just the tonnage.
So the vehicle that served a Penn Slate working is more likely a flatbed with good decking and careful strapping than a tri-axle dump, and it will show handling wear and deck damage rather than hoist and body wear.
There is a paperwork consequence too. Part 46 of the Mine Safety and Health Administration rules covers surface stone operations and requires site-specific hazard awareness training for over-the-road delivery drivers before work at each mine site, so a driver on these lanes carried a training record per site rather than one card for all of them.
Cement and rail, three to eleven miles out
Beyond the slate the valley is cement country. The Amrize Whitehall Plant lies about 7.3 miles south-east with 80 people on the books, and Keystone Cement about 11.2 miles east at Bath with 124.
North it is Palmerton: the Palmerton yard about 3.2 miles and DTA Alliance about 3.6 miles with ten people. The Lehighton yard sits about 7.9 miles north-west at Weissport.
South-east the pits: the Egypt Quarry about 6.7 miles with two people and the Ormrod Quarry about 7.0 miles with 23, and Lehigh Asphalt Paving about 10.1 miles west at New Tripoli with 17.
- The deck and the winches are shot.Expected on a slate flatbed. Around the Egypt Quarry and Lehigh Asphalt Paving we see that pattern and we read it as use, not neglect.
- It came off a cement job.
- I am up towards Palmerton.
Between the Ormrod Quarry about 7.0 miles out and the Egypt Quarry about 6.7 miles out they turn up steadily.
