Prairie White Cliffs Ranch includes riverfront lands, prairie, and the famed White Cliffs that remain much as they did when Lewis and Clark traveled here, retaining a naturally sustained productivity that has defined the area for generations. Over the last 200 years, most settlers passed by on steamboats headed to more hospitable parts of present-day Montana, and only a few remained in this unusually dry and demanding country for long. Nearby stand the remains of a late-1800s stone house built of hand-cut native stone by stonemason Jack Munro, who also rounded up wild horses to sell in Miles City, Montana. In 1900, Gage Clark of New York settled here with his wife and child and built a five-room, two-story frame house whose remains still occupy the river bottom. Since 1981, the present owner's family has used the mostly flat land above the river for some dryland wheat and barley farming, but chiefly for grazing sheep and cattle, while preserving riverfront historic sites and managing livestock grazing to sustain natural vegetation and improve wildlife habitat through a program called Undaunted Stewardship.
