Rock River Ranches is owned by Rex and Julie Moore and their two sons. Rex is a third-generation Rancher, and his grandfather Roy was the first angus breeder in Wyoming back in the 1930's. The family has ranched in Idaho, Oregon, and Wyoming, as well as becoming some of the premier bison ranchers in Colorado. They have herds across Colorado in Hartsell, Wray, and Hudson. Rex and Julie are committed to working with independent local distributors and ship directly to consumers across the country. When demand is high, Rock River Ranches partners with other like-minded ranchers in the region to make sure everyone has access to ethically raised bison.

Rock River bison never receive antibiotics, hormones, or graze on pesticide/herbicide treated pastures, and are never branded. They are fed free-choice hay and grass and are finished on spent grains from local distillers.

Feel free to inquire about pricing on off-cuts and fresh products.
