The Warner Mountains are an 85-mile (137 km)-long mountain range running north–south through northeastern California and extending into southern Oregon in the United States. The range lies within the northwestern corner of the Basin and Range Province, extending from the northeastern corner of Lassen County, California, through eastern Modoc County, California (east of Alturas), and northward into Lake County, Oregon (east of Lakeview).
The highest peak in the range is Eagle Peak with an elevation of 9,892 feet (3,015 m). The range is part of the Modoc National Forest in California and Fremont National Forest in Oregon. The southern portion of the range includes Eagle Peak, within the South Warner Wilderness.
The Warner Range is not part of the Sierra Nevada range or the Cascade Range, but part of the Great Basin Ranges. It is in the semi-arid, sparsely-populated northeastern corner of California and the south-central portion of Oregon. The range is a classic example of horst and graben (fault-block) topography with pluvial (ephemeral) lakes occupying the graben basins.
The eastern escarpment of the range overlooks the Surprise Valley in California and Warner Valley in Oregon, enclosed basins that contain Upper Alkali Lake, Middle Alkali Lake, and Lower Alkali Lake along the California–Nevada border, and the Warner Lakes (Crump and Hart lakes) in Oregon. The western side of the range overlooks a ranching and farming region drained by the forks of the Pit River, a tributary of the Sacramento River. Goose Lake is a 28-mile (45 km) long closed-basin lake located in the Goose Lake Valley along the west side of the range, straddling the California–Oregon border. Goose Lake drained into the Pit River only twice in recorded history: in 1868 and 1881. The lake dried up in 1926 and from 1929 to 1934.
