National Register of Historic Places (Listed, 1979), The Sod House Ranch is a historic ranch in Harney County in southeastern Oregon, United States. The remaining ranch structures are located south of Malheur Lake in the Malheur National Wildlife Refuge. The ranch was built by Peter French, a well known 19th-century cattle baron. The Sod House Ranch became the headquarters for the northern operating division of the French-Glenn Livestock Company, which eventually covered over 140,000 acres (570 km2). After French was murdered in 1897, the French-Glenn Livestock Company slowly sold off its ranch property. In 1935, the United States Government purchased the Sod House Ranch property to add to an adjacent wildlife refuge. The eight remaining Sod House Ranch buildings are now listed on the National Register of Historic Places., National Register of Historic Places Nomination -- Inventory Form
