Pueblo came into existence in 1863, shortly after discoveries were made at nearby Park Canyon. Nothing of consequence was found, and the little camp disappeared as quickly as it appeared. In 1905, a skeleton of a man with a gold pan was found next to a nearby stream. A quick panning of the dirt by the prospector that found the skeleton revealed ore worth $5000 per ton. A camp of sixty tents quickly sprang up, and in March 1906 a townsite was formally platted. Soon more than a dozen wooden buildings were constructed, and the population of Pueblo was nearly 500. The claims were operated by the Marvel Mining Company and the Pueblo Gold Mines Company, but unfortunately the veins were shallow and ore ran out by summer. Pueblo was again abandoned, this time for good.
