Comments on the location information

  • ELEVATION IS 1605 FT ON OLD COPPER TOWN. LATITUDE AND LONGITUDE ON OLD COPPER TOWN ARE 33-16-24N AND 100-02-09W, RESPECTIVELY. F. DAVIDSON SURVEY. N. SIDE OF SALT FORK, ABOUT 2.5 MI W. OF CONFLUENCE OF SALT FORK AND DOUBLE MOUNTAIN FORK OF BRAZOS RIVER. MALACHITE IN SANDSTONE IN QUARRY AT BASE, 8-10 FT THICK. HALE (1977, P. 188-189) SAID THAT A COMMUNITY OF 30 PEOPLE LIVED AT OLD COPPER TOWN, OR ORIENTAL CITY, IN THE LATE 1800'S, NEARBY WHICH 14 MEN WORKED IN THE COPPER MINES. THIS WAS AT THE JUNCTION OF THE SHARP CURVE IN THE ROAD ABOUT 2 MI NE OF THE FARRIS PROSPECT, WHERE THE ROAD TURNS NW TOWARD KROWN PEAK. SUPPOSEDLY, A COPPER MINE WAS DUG 0.25 MI W. OF COPPER TOWN, ABOUT 150 FT N. OF THE ROAD, AT BASE OF SMALL HILL, AS NOTED BY HALE (1977, P. 287).
