The Biscuit Fire was a massive wildfire in 2002 that burned nearly 500,000 acres (780 sq mi; 2,000 km2) in the Rogue River–Siskiyou National Forest, in southern Oregon and northern California, in the Western United States. The fire was named after Biscuit Creek in southern Oregon. The Biscuit Fire was the largest wildfire in the recorded history of Oregon. The Biscuit Fire area is subject to warm, dry winds known as the Brookings effect (also known as Chetco effect), driven by high pressure over the Great Basin. The fire re-burned portions of the 1987 Silver Fire and subsequently burned in the 2017 Chetco Bar Fire.
