Dolan spent 15 months and his own money to create, transport and install the horses as a gift to the people of Montana. When he moved to Montana from California in 1966, he intended to live there permanently and be an asset to the state: "I always knew that someday I’d have a specific project... I decided , on my 64th birthday, this is what I would do." The horse sculptures were installed on Kamp Hill on land donated by Dean Folkvord of Wheat Montana on a patch of unfenced acreage that is not suitable for farming. Folkvord came up with the idea of using Kamp Hill when Dolan stopped into the Wheat Montana Bakery for coffee and expressed frustration to Folkvord about his difficulties finding an appropriate site for installing the horses he was creating.
Development and Installation
The sculptures are realistic enough to appear live from a distance, but are intended to be somewhat "impressionistic." To emphasize the elegance of the horse, the legs of the horse sculptures are one-third longer than those of real horses, and they average high at the withers. Dolan said, "They're symbols of horses and what horses mean to Montanans. But at first sight, I want people to believe they are real horses, just for a second." They are posed in a variety of realistic positions from foals suckling mother's milk, to alert steeds, to supine equines. According to Dolan, "I tried to place the horses the way I see the horses living in their natural environment according to their nature." Twelve of the horses have their heads placed on ball bearings so they are able to move and one can move its head and neck. Each horse is painted blue with accents of black and white to give their forms a sense of depth. They have manes and tails made of polyester rope that has been unraveled and attached so it moves realistically in the wind. The 4,000 feet of rope needed for the horses was unraveled by hand by the employees at Reach, Inc., a supported workplace for people with developmental disabilities. Dolan said, "They really enjoyed doing it, and when I told them what the ropes were for, they felt like they were involved in something bigger than just the job. So those people, they’re part of this, too.” The horses were permanently placed on the land by having long stakes welded to their hooves and placed into holes created with a jackhammer. A tractor was used to place each sculpture in its precise location. In December 2013, three of the sculptures were stolen off the hill but recovered near Townsenda day later. People driving along U.S. 287 can take a dirt road that goes around the back of the herd to view them at closer range. To view the horses from the highway, cars can pull over to the shoulder of the road at the bottom of the hill, and it is possible to walk along the highway to a vantage point at a former pulloff midway up the hill that is now closed to parking.
