History of Malheur County
Malheur County was officially created on February 17, 1887. It was formed from the southern part of Baker County. The first people to settle here were miners and ranchers in the early 1860s.
A big change happened in 1863 when gold was discovered. This brought more people to the area, leading to new towns and farms. Later, in the 1890s, many Basque people moved to the region. They mostly worked with sheep, raising them for wool and meat.
