Some Historical Notes
In 1850, John William Hance discovered a fourteen pound lump of gold atop Carson Hill while supposedly chasing a runaway mule. The lump had broken away from a quartz vein, along which Hance immediately staked his claim. He later took on a group of six partners who then called themselves the Carson Creek Consolidated Mining Company. The claim was generally known as the Morgan Mine, after the most prominent of the partners, Colonel A. Morgan.

His claim was so rich that a unique method of mining was employed here with great success. Borthwick describes the method during the old days: "When the quartz vein was first worked, the method adopted was to put in a blast, and after the explosion, to go round with handbaskets and pick up the pieces." Using this method, $110,000 in gold was collected from a single blast. At another time, a lump of ore was found weighing 112 pounds. And on November 22 of 1854, one of the largest gold nuggets ever found in California was uncovered in the Morgan Mine, very near the surface. Technically not a nugget, but rather a mass of gold and quartz, the thing was huge; fifteen inches long, six inches wide, and four inches thick. It was valued at $43,000 — a mere fraction of Carson Hill’s total production of $26 million.

2,340 ounce mass of gold found in 1854.
