Rock Springs Quarry
Location: unclear. This could be the Riley Quarry. In the spring of 1907 a small quarry was opened by the Verona Mining Company, of Trenton N.J., about 3½ miles northeast of Conowingo. The material here is almost exactly similar in character and mode of occurrence to Bald Friar, and occurs within the same belt of basic rocks (serpentine, pyroxenite etc.). Talc is also obtained at this quarry. The spar is hauled by team 3 miles to Conowingo, from which it is shipped by rail. (Bastin, 1910). This quarry has now been abandoned for a few years. No evidence of commercial feldspar is to be seen, as the pit has been filled by cavings from the walls, this covering the walls. The feldspar mined was a fine grade of albite, but the quantity obtained is reported too small to justify operations. (Watts, 1916) |
