The Great Western Cattle Trail was used during the late 19th century for movement of cattle and horses to markets in eastern and northern states. North Dakota Great Western Trail Chair Darrell Dorgan explains the process of marking the trail, courtesy of a handful of volunteers who placed obelisks and black marble markers from the South Dakota border to Belfield last summer and completed the remainder of the North Dakota portion in its entirety this summer. This weekend, June 26-27, the Great Western Trail will celebrate the momentous undertaking with a grand celebration at Fort Buford. Dickinson Ready Mix, an avid supporter of local nonprofits in western North Dakota, provided the obelisks free of charge to the project — a donation estimated at over $50,000.
