1930 Map of Garfield County.

Located in the northeastern portion of the State of Montana, Garfield County is 4,840 square miles in size. It is bordered on the North by Fort Peck Lake and the Missouri River, as well as by Phillips and Valley Counties. Petroleum County is to the West, Rosebud and Custer Counties lay to the South, and McCone and Prairie Counties are to the East.

Garfield County was created in 1919 out of Dawson County, one of the original sixteen counties at Statehood. Most of Garfield County is drained by Big Dry Creek, mentioned in the Lewis and Clark Journals. Large cattle companies made use of the open range until the late 1880's, when the first fenced ranches began to form. Many of these early ranchers were cowboys employed, or formerly employed, by the large cattle companies. The population of the Big Dry Creek Country increased greatly during the homestead boom between 1900 and 1920. After 1920, the population declined, and Old homestead lands returned to grazing land. Garfield County remains ranch country to the present day. The county seat is Jordan. In 2010, the county had a population of over 1,200.
