Before you, on the east side of Red Mountain Creek, is the headframe of the Yankee Girl Mine.

In 1882, prospector John Robinson discovered a massive "pipe" of silver ore and staked the Yankee Girl claim. He developed an exploratory shaft and found that the nearly vertical ore body contained an enormously valuable vein of silver.

Unlike most local mines, the Yankee Girl shaft went nearly straight down - 1200 vertical feet. Eventually, twelve levels were developed below ground. In places, silver ore assayed as high as $10,000 per ton making the Yankee Girl one of the richest concentrations of silver ore in the United States. Ore from the mine was of such a high grade that it bypassed the concentration mill and went directly to the smelter for processing.

As the miners descended into lower and lower levels, mechanical "bailers" were installed to remove water from the mine. Yet even with new technology a decrease in the value of silver forced the Yankee Girl to close in 1898. During its sixteen years of operation it produced nearly twelve million dollars in ore. The value of the ore in today's market would
