Worth Brothers Quarries

---

Location: east of Pilot, alongside Pilot Town Road.

One-half mile east of Pilot is a small opening with a length of 100 feet in a direction N. 70° W. and 20 feet wide, owned by Worth Brothers which has been idle for nearly 15 years. This feldspar contains more or less quartz in fine graphic intergrowths, small flakes of white mica, and a little tourmaline. There is also some coarse striated feldspar with large blades of mica. The large piles of rejected material indicate an unusually poor grade of rock. The wall rock is serpentine. (Maryland Geological Survey, volume 12, 1928)
