Silver Reef is a ghost town in Washington County, Utah, United States, about 15 miles (24 km) northeast of St. George and 1 mile (1.6 km) west of Leeds. Silver Reef was established after John Kemple, a prospector from Nevada, discovered a vein of silver in a sandstone formation in 1866. At first, geologists were uncertain about Kemple's find because silver is not usually found in sandstone. In 1875, two bankers from Salt Lake City sent William Barbee to the site to stake mining claims. He staked 21 claims, and an influx of miners came to work Barbee's claims and to stake their own. To accommodate the miners, Barbee established a town called Bonanza City. Property values there were high, so several miners settled on a ridge to the north of it and named their settlement Rockpile. The town was renamed Silver Reef after silver mines in nearby Pioche closed and businessmen arrived.
