Ranch, established in 1885 in Carbon County, Wyoming.

The ranch operated under the Spanish tradition of low-altitude winter ranch and high-altitude summer range.

The ranching operation expanded greatly after the hard winter of 1886-87 devastated the cattle ranching industry in the area.

Construction is log and stone, with many well-preserved structures.
