Mount Owen Rifle Range
The site is located in Fresno County, approximately six miles northeast of Clovis, California.
Between 1942 and 1944, the U.S. Army acquired use of 1,654.43 acres for use as a rifle range. Site improvements included: a deep water well and interconnecting water pipeline embedded under a county roadway; a rifle range including five earth berms and a concrete retaining wall; and former barracks including a mess hall, showers, latrines, a sewage system, and two concrete 1,000-gallon underground storage tanks.
The site was declared surplus by the War Department in 1946 and all leaseholds and licenses terminated in 1947. Records indicate that the barracks were closed and partially dismantled after termination of the lease.
The rifle range consists of five linear, parallel earthen berms approximately 300 feet apart. Each berm is about 600 feet long, 7 feet high, and 7 feet wide.
