The Biscuit Fire was a massive wildfire in 2002 that burned nearly 500,000 acres 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, 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.

The Blue Ledge Mine is an inactive underground copper mine that has been classified as a Superfund Site by the Environmental Protection Agency (EPA) due to high concentrations of heavy metals. The mine is located approximately 3 miles south of the California–Oregon border in the Rogue River-Siskiyou National Forest. It is within the Siskiyou Mountain range, and sits near a summit at about 4,800 feet above sea level.

The Chetco River is a 56-mile-long (90 km) stream located in the southwestern portion of the U.S. state of Oregon. It drains approximately 352 square miles (912 km2) of Curry County. Flowing through a rugged and isolated coastal region, it descends rapidly from about 3,200 feet (975 m) to sea level at the Pacific Ocean. Except for the lowermost 5 miles (8 km), the river is located entirely within the Rogue River – Siskiyou National Forest. The river rises in the Kalmiopsis Wilderness, northwest of Chetco Peak at the junction of the Oregon Coast Range and the Klamath Mountains. It flows generally north, west, and then southwest, before emptying into the ocean between Brookings and Harbor, approximately 6 miles (10 km) north of the California state line. The Chetco River's watershed remains largely undeveloped, protected by the Rogue River – Siskiyou National Forest and the Kalmiopsis Wilderness. The upper 45 miles (72 km) of the river have been designated Wild and Scenic since 1988.

The Copper Salmon Wilderness is a protected wilderness area in the Southern Oregon Coast Range and is part of the Rogue River–Siskiyou National Forest.

The Klamath Basin is the region in the U.S. states of Oregon and California drained by the Klamath River. It contains most of Klamath County and parts of Lake and Jackson counties in Oregon, and parts of Del Norte, Humboldt, Modoc, Siskiyou, and Trinity counties in California. The 15,751-square-mile (40,790 km2) drainage basin is 35% in Oregon and 65% in California. In Oregon, the watershed typically lies east of the Cascade Range, while California contains most of the river's segment that passes through the mountains. In the Oregon-far northern California segment of the river, the watershed is semi-desert at lower elevations and dry alpine in the upper elevations. In the western part of the basin, in California, however, the climate is more of temperate rainforest, and the Trinity River watershed consists of a more typical alpine climate.

The Klamath River flows 257 miles (414 km) through Oregon and northern California in the United States, emptying into the Pacific Ocean. By average discharge, the Klamath is the second largest river in California after the Sacramento River. It drains an extensive watershed of almost 16,000 square miles (41,000 km2) that stretches from the arid country of south-central Oregon to the temperate rainforest of the Pacific coast. Unlike most rivers, the Klamath begins in the high desert and flows toward the mountains – carving its way through the rugged Cascade Range and Klamath Mountains before reaching the sea. The upper basin, today used for farming and ranching, once contained vast freshwater marshes that provided habitat for abundant wildlife, including millions of migratory birds. Most of the lower basin remains wild, with much of it designated wilderness. The watershed is known for this peculiar geography, and the Klamath has been called "a river upside down" by National Geographic magazine.

Lewisia cotyledon is a species of flowering plant in the family Montiaceae known by the common names Siskiyou lewisia and cliff maids. It is native to southern Oregon and northern California, where it grows in rocky subalpine mountain habitat.

The North Fork Smith River is 28-mile (45 km) tributary of the Smith River that begins in the U.S. state of Oregon and ends in the U.S. state of California. Arising near Chetco Peak in the Klamath Mountains, it flows generally south to meet the Middle Fork Smith River at Gasquet, California. The combined streams form the Smith River.

The Red Buttes Wilderness is a wilderness area in the Klamath and Rogue River national forests in the U.S. states of Oregon and California. It comprises 19,940 acres (8,070 ha), approximately 16,190 acres (6,550 ha) of which is located in California, and 3,750 acres (1,520 ha) in Oregon. It was established by the California Wilderness Act of 1984 and the Oregon Wilderness Act of 1984.

The Rogue River in southwestern Oregon in the United States flows about 215 miles (346 km) in a generally westward direction from the Cascade Range to the Pacific Ocean. Known for its salmon runs, whitewater rafting, and rugged scenery, it was one of the original eight rivers named in the Wild and Scenic Rivers Act of 1968. Beginning near Crater Lake, which occupies the caldera left by the explosive volcanic eruption and collapse of Mount Mazama, the river flows through the geologically young High Cascades and the older Western Cascades, another volcanic province. Further west, the river passes through multiple exotic terranes of the more ancient Klamath Mountains. In the Kalmiopsis Wilderness section of the Rogue basin are some of the world's best examples of rocks that form the Earth's mantle. Near the mouth of the river, the only dinosaur fragments ever discovered in Oregon were found in the Otter Point Formation, along the coast of Curry County.

The Rogue–Umpqua Divide Wilderness is a wilderness area located in the Rogue River – Siskiyou and Umpqua National Forests in the Klamath Mountains of Oregon, United States. It was established by the United States Congress in 1984 and comprises 33,200 acres (13,400 ha).

The Siskiyou Mountains are a coastal subrange of the Klamath Mountains, and located in northwestern California and southwestern Oregon in the United States. They extend in an arc for approximately 100 miles (160 km) from east of Crescent City, California, northeast along the north side of the Klamath River into Josephine and Jackson counties in Oregon. The mountain range forms a barrier between the watersheds of the Klamath River to the south and the Rogue River to the north.

The Siskiyou Wilderness is a federal wilderness area designated by the passage of the California Wilderness Act of 1984. Originally, the land area was 153,000 acres (620 km2) The Northern California Wild Heritage Act of 2006 added 30,122 acres (121.90 km2) for the current total of 182,802 acres (739.77 km2). All of the wilderness is in Northern California and is managed by the U.S. Forest Service. The wilderness spans three national forests: the Rogue River–Siskiyou, the Klamath, and the Six Rivers.
