At the turn of the twentieth century, hard rock mining in Boulder County was in full swing, and the area known as Wall Street played a prominent role in this chapter of our community’s history. The assay office was the place where prospectors would take their ore samples to find out whether or not they had potentially “struck it rich.” So important was the determination of the assayer that the results of their work could, and often did, make or break a prospector.
