Mines and mineral resources

According to Horace Waters, the family of Meyers Harris was in Boulder during the 1870s and 1880s. He and his wife Jeanett had four daughters (Anna, Sarah, Etta, Rebecca), all of whom were born in Michigan before the family moved to Colorado. The families of Benjamin, Moses, and George B. Holstein were in Boulder and Blackhawk during the 1870s and 80s, where they were involved in the clothing and mining industries (specifically the Cohen Lode).
