The history of Broken Boot Gold Mine is connected with the life of Olaf Seim, who looked for valuable ores in the area with his friend James Nelson around 1880. He discovered a little gold, but also fool's gold, graphite, silver, copper sulfate, and quartz. The so-called fool's gold is iron pyrite, an iron ore. Many of the ores in the mine are sulfuric, and the success of the mine was the production of sulfuric acid from this sulfur, which was used frequently in the processing of gold. He was so successful, he soon had exhausted the mine and it was closed.

The mine was reopened as a show mine by Olaf Seim's daughter, Selma Herbert, in 1954. As an tourist attraction it earned more money than by selling the minerals.
