Plaster City is a company town with a large gypsum quarry and plant owned by United States Gypsum (USG)[1] in Imperial County, California. It is located 17 miles (27 km) west of El Centro,[1] at an elevation of 105 feet (32 m), a two-hour drive south of Palm Springs, or a 90 minute drive east from San Diego.[2]

The quarry and supporting railroad were started in 1920 by Imperial Valley Gypsum and Oil Corporation founder Samuel Dunnaway, a pharmacist from San Diego,[2] then acquired by United States Gypsum in 1945.[3] Plaster City is the southern terminus of the last industrial narrow gauge railroad in the United States. The 3 ft (914 mm) gauge line runs from another quarry about 22 miles (35 km) miles to the northwest, bringing gypsum to the plant.[4][5][6]

The first post office at Plaster City opened in 1924.[1] The ZIP Code is 92251.

Plaster City is surrounded by two Off-Highway Vehicle Areas operated by the Bureau of Land Management: Plaster City West Off-Highway Vehicle Area and Plaster City East Off-Highway Vehicle Area.[7]
