Camp Warner was a United States Army outpost in south-central Oregon. The Camp was located at two different sites approximately 35 miles apart. “Old” Camp Warner was built 15 July 1866, 20 miles east of Warner Lake in what is today Lake County. It was a temporary facility, hastily built to accommodate troops for the coming winter. The conditions were harsh, and night temperatures too low inside the buildings. When Lieutenant Colonel George Crook, 23rd U.S. Infantry, arrived in the spring of 1867, he ordered the camp to be moved west of the initial location to a lower elevation. The Camp was moved 1 September 1867 to a point 15 miles west of Warner Lake and 35 miles from Oregon-California state line. The “New” Camp Warner was also called Fort Warner, and was used as a supply depot and administrative headquarters during an Army campaign against Northern Paiutes in Eastern Oregon and Northern California. It was abandoned 3 September 1874. The Camps were named after Captain William H. Warner, a topographical engineer who was killed by Indians in 1849 in California near the Oregon border.
