The Stock Association of Laramie County was organized in Cheyenne in 1872 to combat cattle rustlers operating in the area.

In 1883 Alexander H. Swan founded the Wyoming Hereford Association, the predecessor of the Wyoming Hereford Ranch, to establish a pure bred Hereford herd in Wyoming. The ranch was situated in Laramie County, Wyoming, on Crow Creek. Swan went bankrupt in 1887, a disastrous year for ranchers due to bad weather conditions, and the herd was taken over by Henry Altman and Dan McIllvain of Cheyenne, who bought the then 30,000 acre Crow Creek ranch and the herd in 1890. They owned and operated it for twenty-seven years under the name Wyoming Hereford Association.

Frewen served as manager of the company until 1886. The company was dissolved in 1889 due to overstocked pastures and harsh winters.

Dude Ranch

Dude Ranchers Association Records

The Dude Ranchers' Association was formed in Billings, Montana, in 1926 when the Northern Pacific Railway met with a group of dude ranchers to work together to promote the ranches and tourism. The association studies issues like taxation, insurance, legislation affecting the administration of public lands, and fish and wildlife conservation. It works to preserve the qualities of isolation, remoteness, and unmodified nature in wilderness areas and national forests to sell the dude ranch vacation as the only venue that can simulate the American frontier experience.
