How did Marmarth get its name?
The name comes from a combination of letters in the first and middle names of Margaret Martha Finch, granddaughter of Albert J. Earling, president of the railroad at the time.
The area was originally inhabited by the Lakota- and Crow peoples, which may have been part of the 9th–12th centuries BCE Mound Builders civilization.
On September 2, 1864, Captain James L. Fisk of the Union Army was leading 200 gold-seekers in eighty-eight wagons from North Dakota to Montana. By the Deep Creek, approximately twelve miles east of today's Marmarth, the group was attacked by over a hundred Hunkpapa Sioux Indians led by the chief Sitting Bull. Sitting Bull was wounded, but saved by Jumping Bull and White Bull, while six Hunkpapas, ten soldiers, and two civilians were killed in the battle. The Site of Fort Dilts has been listed on the National Register of Historic Places since 1980.
