Historic Horse Ranch in Pueblo County Now Under Permanent Protection

The historic Stewart Thoroughbred Horse Ranch located in Colorado City, in the Greenhorn Valley, has been protected, forever, with a conservation easement held by San Isabel Land Protection Trust. Thanks to the MacCormack family who donated the conservation easement to the Land Trust, this action ensures that the land will continue to be used as a horse and agricultural property as it has been for over 50 years.

This unique horse ranch lies at the bottom of the Greenhorn Valley and is almost completely surrounded by densely subdivided parcels within Colorado City. The 213-acre jewel provides a semi-urban oasis of riparian forests along Greenhorn Creek and provides scenic open space to travelers along Colorado Highway 165, which is part of the nationally-designated Frontier Pathways Scenic Byway. Visible from Interstate 25, the grass prairie and riparian forests offer sweet refuge to Pronghorn, White-Tailed Deer, Coyote, Red-Tailed Fox, Mule Deer, Black Bear, and numerous other species.

The Ranch enjoys a colorful history and has been operated as a commercial thoroughbred horse ranch since 1959, when it was first purchased by Holland Duell and Conyers Stewart. Originally called “Duell-Stewart Thoroughbreds,” the name was later changed to “Stewart Thoroughbreds Horse Ranch.” The current landowner purchased the Ranch in 2002 and since its inception has hosted numerous race events for both thoroughbreds and quarter horses. At least four horses kept on the Property were descended from the famous race horse “Man of War.”

The former race tracks are still visible today, with the thoroughbred track still receiving occasional use. Most of the structures on the ranch were built to support the thoroughbred operation. Today, the property is primarily use for horse boarding and grazing, and seasonal cattle grazing.
