Weiant Feldspar and Serpentine Stone Quarry

Location: west bank of Conowingo Creek, northeast of Pilot, Cecil County, Md.

Ten years ago F. S. Weiant opened a feldspar quarry on the west bank of Conowingo Creek. 1 mile northeast of Pilot which has now been idle several years. When first opened a dike about 15 feet wide in serpentine with a serpentine horse in the middle was exposed. The feldspar was practically free of mica and contained no quartz, but occasionally showed radiating tufts of actinolite. The rock was being shipped to Golding Sons Company. The opening as it stands today is about 75 feet long in the direction N. 15° W. and about 50 feet wide. The center is full of water to within 25 feet of the top. At the north end the dike split to 2 branches separated by about 12 feet of serpentine. The west branch is 15 feet wide and the east branch 23 feet wide. The quarry has produced about 3500 tons of feldspar. (Maryland Geological Survey, 1928)
