They found gold in the ravine near an elevated area they named Gold Hill. In addition to the gravel deposits, the hill itself was developed by two companies, known as the Georgia and the Ohio, using ground sluicing from water in the ravine. The town's civil government was organized in the spring of 1852, with the election of a Justice of the Peace, and a Constable. The population of the mining community peaked in 1856.
