General Description

The SweetGrass Ranch is located at the edge of the Black Hills and the Thunder Basin National Grassland. After entering the ranch on the north, one heads south past the indoor riding arena and managers home and into the main building compound. From there a series of private two-tracks can take you anywhere on the ranch. Virtually all directions from the compound take you into pine ridges and areas of heavy forest.

However, the town has taken advantage of the influx of mineral related money and has built some wonderful infrastructure which the locals and surrounding ranchers continue to enjoy. Gillette is the home to a community college, a hospital, several churches, numerous restaurants, shopping, and a complete array of commercial services, as well as a full menu of social and cultural events.

The Cam-Plex Theater is a state of the art venue where national productions are performed each year. The location of the SweetGrass ranch truly gives you the best of both worlds, close to one of Wyoming’s bigger communities, yet totally private and secluded.

Aesthetic Considerations

The SweetGrass Ranch is a one of a kind listing, offering a wild but user-friendly landscape that is intrinsically beautiful in its own right and evokes the image of what a classic Wyoming ranch should look like.


The Campbell County and the Black Hills are areas rich in western history. What is now Campbell County, stretching from the Black Hills in the east and near the Big Horn Mountains in the west, it was the perfect habitat for the North American Bison as well as other large mammals making it ideal hunting ground for Native American tribes: Cheyenne, Kiowa, Pawnee, Crow, and the Lakota Sioux nations. Next fur trappers and traders of European descent moved into the area around 1805 with the arrival of the first explorer-trapper, Francois-Antoine Larocque. In the 1860’s cattle drives were a common occurrence in the area as cattle were trailed from Texas to Montana, and shortly thereafter cattle ranches were established in Campbell County. During this same time the discovery of gold lead to the gold rush in the Black Hills and men also traveled through the area to the gold fields in California. Later years found the discovery of oil and coal which has played a significant role in the area’s history as well as in its current economy.

General Operations

The SweetGrass Ranch is the definition of western luxury and recreation in an extremely private location. The improvements lend themselves to the possibility of a guest ranch that could be used for personal or company retreats. Naturally it also offers a perfect family retreat nestled in the midst of the beautiful Black Hills. For those who are seeking privacy and yet desire to be within an hour of fine amenities, the SweetGrass Ranch is the ideal location. The indoor arena/horse barn allows for the raising and training of horses or simply as a base for owning and enjoying riding horseback over the rugged and beautiful Wyoming landscape. The ranch is large enough to handle a sizeable livestock operation if one is so inclined. The current owners of the SweetGrass Ranch have been lightly using the ranch with a registered horse operation; not necessarily operating with a large number, but keeping a small package of extremely high quality brood mares. If a buyer is inclined to run cattle on the ranch, the ranch is cross-fenced multiple times and has a good distribution of water throughout for livestock. Based on county stocking averages, the ranch should comfortably support 150-200 pairs, or 500-600 yearling stockers for the summer grazing season. In addition to the grazing lands of the ranch, there are also a few dryland hay fields, totaling approximately 50 acres. These work well for additional grazing forage or creating better habitat for wildlife.
