Two rather small quarries in Stone Mountain granite, located about three and a half miles southeast of the village of Stone Mountain, are owned by Mr. Bates Block of Atlanta. The larger of the two quarries is only a few hundred feet east of the Wade residence. The smaller one is in a flat-rock exposure about five acres in area, several hundred yards south of the large quarry near the headwaters of Crooked Creek.
The rock is gray-white granite remarkably free from blemishes or inclusions. It contains about twice as much muscovite as brownish biotite. Structures are not pronounced in the rock, but a faint flowage foliation trends N5°W and dips 40 °E. A strong set of joints strikes N35 °W and dips vertically.
