Of 36 counties in the Beaver State, Malheur County ranks second in terms of size (6 million acres). Malheur County is in the Eastern Oregon region. Tucked away in the southeastern corner of Oregon, over 90 percent of Malheur County is rangeland, with the Bureau of Land Management controlling almost three-quarters of this land. With an economy that is dependent on agriculture, and tourism to a lesser degree, the most intensive farming occurs in the northeastern part of the county in what is known regionally as ?Treasure Valley? (a nickname given to the fertile area fed by the Snake River and its various tributaries, including the Owyhee River and irrigation through the Owyhee River dam). Malheur County is also known for its distinctive volcanic buttes and the striking high-desert canyons carved by the passage of ancient rivers across the landscape.
