Geography and Area Information


The Sierra Army Depot is located at 40°15′58.19″N 120°09′09.43″W in the unincorporated community of Herlong California directly off of State Highway 395 and covers 36,000 acres (56.25sqmi). Due to the nature of the Depots mission the installation is located in a rather remote section of California. The Sierra Army Depot lies just north of Patton Village and Highway 395 and the northern border lies at the base of Hot Springs Peak, a 7654ft mountain in the Skedaddle Wilderness Study Area. The Eastern border is marked by the California Nevada State line and the western border marked by the dry lakebed of Honey Lake. The terrain of the Sierra Army Depot is composed primarily of arid Great Basin desert that quickly transitions into the mountains of the Skedaddle Wilderness Study Area to the northeast. Temperatures in this area can swing dramatically year round with summer daytime temperatures reaching well into the triple digits and nighttime temperatures approaching freezing.



The Sierra Army Depot was established in 1942 to be storage facility for general supplies and Treasury Department material. The location was picked for its proximity to the coast while still being far enough inland to avoid potential Japanese attack and arid climate. Following World War II the mission of the Sierra Army Depot was expanded to include munitions, both live and demilitarized for the Korean War conflict. Throughout the Vietnam War and well into Operation Iraqi Freedom and Operation Enduring Freedom the Sierra Army Depot played a vital role in shipping containers of supplies overseas as its mission expanded to include tactical vehicles, both wheeled and tracked, fuel systems, hospital supplies and maintenance equipment.
