The Colorado town of Tin Cup was a crazy one in the mining days. Gold attracted all sorts of attention to the region and in 1913 the Tin Cup Gold Dredging Company required electric power to make dredging profitable. They built a hydroelectric plant in St. Elmo and had a 16,500-volt transmission line over a high mountain pass. By 1917, the business was in a financial panic and the whole dredging operation collapsed and was sold off, including the power plant equipment and transmission line.
