History
Formed in 1889 from Garfield County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Rio Blanco County was created from Garfield County on March 25, 1889. It was named after the White River. By 1930, Rio Blanco lost territory to Routt County when the boundary was shifted to public land survey lines.
