In the mid-1860s, stories spread of a rich silver lode in Nevada. Thousands of treasure seekers arrived from all points of the compass, and by 1870, the mining camp became one of the largest cities in the West outside of San Francisco. For years, wealth poured from its surrounding hills as if from a broken tap. When the bonanza inevitably ended, the town lived on and weathered another century and a half. Today, it is a rare living artifact of the 19th century.
