Stony Point is about 35 miles southeast of the Blue Ridge, and 16 miles northeast of Statesville. The surface of the country is rolling, the elevation being about 1000' AMSL. The soil is generally a red, gravelly clay, resulting from the decomposition of the gneissoid rock. Unaltered rock appears at a depth of 26 feet and is unusually hard, especially along the walls of the gem-bearing pockets which form in veins of quartz that traverse the gneiss. These veins are usually quite narrow, and generally strike east and west, and dip to the north. Some of the veins widen out occasionally and form cavities several inches wide and several feet in length, or in rare cases much larger.
