History

Herlong was developed in 1942 after the attack on Pearl Harbor during World War II, to house civilian workers to support the Sierra Army Depot, one of several ammunition storage facilities located inland in order to be safe from Japanese attack. The site also met the requirement of being a dry and isolated area. The community was named after Captain Henry W. Herlong, the first United States Army ordnance officer to die in World War II. The postal stamps, money orders and equipment bore the spelling “Hurlong”, which lasted for about five days; the error was discovered and corrected.

In the 21st century, Sierra Army Depot serves as the Army’s End of First Life Center and the CONUS-based Army Prepositioned Stock Site. It continues to provide expeditionary logistics support and long-term sustainment solutions.

Since its beginning, the town has varied in size. Its population peaked at about 5,000 in the 1950s, consisting mostly of civilian employees on the base and their families. As of the 2010 census, the community had 298 people.

Herlong has several churches, including the Bible Baptist Church, Assembly of God, and Southern Baptist. The State Office of Historic Preservation lists 62 historic properties in Herlong on its Historic Properties Data File for Lassen County. This is one of the last counties in California that is still considered to be “open range” land.
