The Smith River, flowing north near White Sulphur Springs, Montana, is one of this country's wildest and most scenic waterways, and it's the location for a ranch shared by two families. The owners have traveled the world, and built the compound to provide a place to gather and relax. The feel is Montana rustic, but with a degree of the contemporary that eases their transition from urban environments. The exterior blends with the landscape by relying on aged materials designed to gray and weather naturally. The interior walls are plaster, with dark wood flooring and cabinetry and beams that contrast. The result is a comfortable balance between country and city, set in one of the most pristine parts of Montana.
