History

Historically, the Kalmiopsis Wilderness was a mining district. Gold was discovered about 1850, causing a gold rush into the area. A number of mining towns were built and more than a dozen hard rock mines were started. Many people lived there up into the mid-1940s. In 1962, many of the homes and stores were still habitable and all the mining equipment and buildings were still in place. The wilderness area was established in 1964. In 2002, lightning started the
