Marmarth (/ˈmɑːrməθ/ MAR-məth) is the largest city in Slope County in the U.S. State of North Dakota with a population of 143 as of 2014. It is situated in the southwestern part of Slope County, along the Bowman County-limits, in the southwestern part of North Dakota, just seven miles east of the state-border to Montana. Marmarth was founded as a railroad town along the Milwaukee Road from Seattle, WA to Chicago, IL, in order to develop a town for homesteaders. By its founding, the town population was over 5,000 people—mostly rail workers and cattle ranchers. Despite a population boom caused by the opening of the Little Beaver Dome oil field in 1936, the town population declined during most of the 21st century and had a population of only 143 in 2014. There is one restaurant and one bar still located in Marmarth in 2013.
It is located between Bucklin township and Hughes township in the badlands region of North Dakota. It is situated adjacent to the Little Missouri River at the confluence of Little Missouri River, Hay Creek, and Little Beaver Creek. It has an elevation of 2,709 feet and is nicknamed “the city of trees” for being an oasis of trees in the treeless Badlands region, and is the only place in the State of North Dakota where limber pines grow.
