Marshall County is a county in the northwestern part of the U.S. state of Minnesota. As of the 2020 census, the population was 9,040.[2] Its county seat is Warren.[3]
The Minnesota legislature created the county on February 25, 1879, with territory partitioned from the southern half of Kittson County, with Warren (which was first platted that same year) as the county seat. It was named for William Rainey Marshall, who served as Minnesota governor from 1866 to 1870.[4]
Marshall County was the location of a claimed UFO incident in 1979, the Val Johnson incident.
Marshall County lies on Minnesota's border with North Dakota (across the Red River, which flows north along the county's western border). The Snake River rises in Polk County and flows north through the western part of the county to its confluence with the Red. The Tamarac River rises in Marshall County and flows west through the county's northern area to its confluence with the Red. The Middle River also rises in Marshall County and flows west through the southern part of the county, discharging into the Snake just upstream of the Snake/Red confluence. The county terrain consists of low rolling hills, carved with drainages, completely devoted to agriculture where possible.[5] The terrain slopes to the west and north, with its highest point near the midpoint of its eastern border, at 1194feet ASL.[6] The county has an area of, of which is land and (2.1%) is water.[7] Marshall is one of 17 Minnesota savanna region counties where savanna soils predominate.
