Malheur County /mælˈhɪər/ is a county located in the southeast corner of the U.S. state of Oregon. It is included in the eight-county definition of Eastern Oregon. As of the 2010 census, the population was 31,313.[1] Ontario is the largest city and the county seat is Vale.[2] The county was named after the Malheur River, which runs through the county. "Malheur" is French for misfortune.

Malheur County is part of the Ontario, OR–ID Micropolitan Statistical Area.

History[edit | edit source]

Malheur County was created February 17, 1887, from the southern portion of Baker County. It was first settled by miners and stockmen in the early 1860s. The discovery of gold in 1863 attracted further development, including settlements and ranches. Basques settled in the region in the 1890s and were mainly engaged in sheep raising.

Geography[edit | edit source]

According to the U.S. Census Bureau, the county has a total area of 9,930 square miles (25,700 km2), of which 9,887 square miles (25,610 km2) is land and 43 square miles (110 km2) (0.43%) is water.[3]

Time zones[edit | edit source]

Most of Malheur County (shown in purple) is in the Mountain Time Zone; a small portion in the southern part of the county is in the Pacific Time Zone along with the rest of the state of Oregon and neighboring Nevada.

Because of its economic relationship with Idaho, most of the county is in the Mountain time zone, making it the only county in Oregon that does not completely follow Pacific Time. The largely unpopulated southern quarter of the county, near McDermitt, observes Pacific Time. The legal dividing line between the two begins at the southwest corner of township 35 S, range 37 E and continues east to the Oregon–Idaho border, at a latitude of approximately 42.45° N. Malheur is one of the few counties in the U.S. that legally observes two different time zones.[4]
