Mentryville was an oil drilling town in the Santa Susana Mountains in Los Angeles County, California, USA. It was started in the 1870s around the newly discovered oil reserves in that area. The first oil strike was on September 26, 1876. The town is located at the terminus of Pico Canyon Road, four miles west of the Lyons Avenue exit from I-5 in Santa Clarita.History"Pico Number 4", a short distance up the canyon from Mentryville, was the first commercially successful oil strike in California, and the longest running well on record, finally being capped in 1990. The Pico Canyon oil field proved to be the richest in the state's history to that time, and Mentryville became a boomtown from 1876 to 1900. The town was named after the superintendent who was in charge of the oil field, Charles Alexander Mentry. Mentry lived in the town until his death in 1900 and built the 13-room mansion that still stands there. In 1900, the Los Angeles Times described Mentryville as "an ideal community of modest homes," where families were reared and a schoolhouse, social hall, bakery, boarding houses, bunkhouses, blacksmith shop and machine shop were built. There was also a gas-lighted tennis court, croquet fields, and a main road paved with local asphalt. One thing the town lacked was a bar. Mentry had reportedly "imbued the town with his puritanism as well as his name," prohibiting drinking and the use of foul language. When Mentry died, the entire town of more than 200 people, except for three individuals left behind in Mentryville, traveled to Los Angeles for his funeral, bringing with them a large floral arrangement in the shape of an oil derrick.
