History

Formed in 1877 from Grand County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Routt County was created on January 29, 1877, from Grand County, though the boundary between the two counties was disputed until a District Court decision in July 1891. The county was named after John Long Routt. In 1911, Routt County lost territory to the creation of Moffat County, and by 1930, it gained land from Garfield County and Rio Blanco County when boundaries were adjusted to match public land survey lines.

Boundary changes from the Newberry Library, Atlas of Historical County Boundaries.
