Namesake The range was named after explorer Captain William H. Warner, of the U.S. Army Corps of Topographical Engineers, who was killed in the range by Native Americans on September 26, 1849, while exploring a route for potential railroad crossings of the Sierra Nevada. His remains were never found and his name appeared on maps of the range in 1866. Camp Warner was established in the northern portion of the Warner Range in Oregon in 1867 by General George Crook to "pacify" the Indians. The post was abandoned in 1874. Crook Peak, elevation in the Warner Range near Camp Warner, is named after Crook.
