Overview
Where California's oil began

Mentryville sits at the end of Pico Canyon Road in the Santa Susana Mountains, off I-5 at Lyons Avenue. In 1876 a crew working for Demetrius Scofield and Charles Alexander Mentry finished a well here called Pico No. 4. It came in on September 26 at 30 barrels a day, and after it was deepened to 600 feet it made 150. It was California's first commercially productive well, and its success led to the Pacific Coast Oil Company, a forerunner of Standard Oil of California.
The town took the superintendent's name. Mentry built a 13-room house and ran a sober place: the Los Angeles Times described modest homes, a schoolhouse, a social hall, a bakery and boarding houses, but no saloon. When he died in 1900, the town of more than 200 people went to Los Angeles for his funeral. The oil slowed, and in the 1930s most families left, many taking their houses with them plank by plank. Pico No. 4 kept pumping until it was capped in 1990.
A caretaker named Frenchy Lagasse saved what was left. He persuaded Standard Oil not to bulldoze the town in the 1960s and began giving tours. After the 1994 Northridge earthquake Chevron gave the site and about 800 acres of the canyon to the Santa Monica Mountains Conservancy. It is now a park with trails and a $5 parking fee.
Timeline
From Pico No. 4 to a public park


- Charles Alexander Mentry, a French-born driller, partners with others on the lease that becomes the Pico Oil claim in Pico Canyon.
- Pico No. 4 is completed at 300 feet, flowing 30 barrels a day. Deepened to 600 feet later that year, it makes 150 barrels a day. It is California's first commercially productive well.
- Mentryville is a boomtown. The Pico Canyon field is the richest in the state to that time. The town gets a school, social hall, bakery, boarding houses and shops, but no bar.
- Mentry dies. More than 200 people live in town, and almost all of them travel to Los Angeles for his funeral.
- Production has slowed and most families leave, many taking their houses apart board by board.
- A ghost town, with only a caretaker family in Mentry's house.
- Caretaker Francis "Frenchy" Lagasse moves in and talks Standard Oil out of razing the town. He restores it and offers tours.
- Pico No. 4 is capped, after 114 years.
- The Northridge earthquake damages the house and Lagasse leaves. Chevron donates the town and about 800 acres of Pico Canyon to the Santa Monica Mountains Conservancy.
- A fire nearly destroys the historic buildings. A storm the next year washes out the parking lot and floods them.
- A park run by the Mountains Recreation and Conservation Authority. California Historical Landmark No. 516-2.
What's here
A house, a school and a barn


The state marker lists what survives: Mentry's restored house, his barn and the Felton School. MRCA calls the house a thirteen-room mansion and the school a one-room schoolhouse. Pico No. 4, marked as landmark No. 516, is a short distance up the canyon. A paved road leads out of the town to the backcountry trails, which are open to hikers, cyclists and riders.
The buildings have had a hard time. A fire nearly destroyed them in 2003, and a storm in 2004 flooded them and washed out the parking lot. The Friends of Mentryville say regular tours stopped after the fire and flooding; nonprofit groups can still arrange special tours by email. A 2013 local commentary complained that the house was off-limits to the public. Expect to see the buildings from outside.
The historic maps below show the canyon from 1903 on. The 1903 Santa Susana and 1940 Pico sheets name the town Pico and show a row of buildings along the canyon road. The 1952 Newhall sheet labels it "Pico (Site)", with water tanks beside it and oil wells and tanks across the ridge to the north.

On location
A film set in the hills
Mentryville and Pico Canyon are a popular location. Wikipedia lists Steven Spielberg's The Color Purple and Walking Tall Part 2, and episodes of The X-Files, The A-Team, Murder, She Wrote and Highway to Heaven. Commercial filming and photography need a permit from the Mountains Recreation and Conservation Authority.

Day trip itinerary
The essentials, the sample day with boxes to tick, what to photograph and the coordinates, on two printable pages. Handy where there's no signal.
Download the PDF (657 KB)Mentryville is a short hop from Santa Clarita, and an easy half day from Los Angeles. Walk the old town, then add a hike up the canyon trails if you want a longer outing. Bring a picnic: MRCA lists picnic tables, but no food.
A sample day
- Leave Newhall on Lyons Avenue, which becomes Pico Canyon Road. The drive takes about 15 minutes.
- Park, pay the $5 fee and walk the old town: the barn by the entrance, Mentry's house and the Felton School.
- Walk up the canyon to the Pico No. 4 well site, California's first commercially productive well.
- Continue up the trail to Johnson Park, a picnic spot 0.7 mile from town that the Friends of Mentryville say the oil men favored, or picnic at the park's tables.
- Head back to Santa Clarita for lunch.
Coming from Los Angeles? It's under an hour without traffic. Leave by 8:15 a.m. to arrive at 9.
What to photograph and film
- The barn and main street. The red barn by the entrance gate frames the town against the hills.
- Mentry's house. Step back across the yard to fit the whole 13-room house in.
- Felton School. The one-room school and its outbuildings make a tidy group portrait.
- Oil equipment. Rusting tanks and wagon wheels beside the Felton School are good for close-ups and slow pans on video.
- Drones. MRCA park rules don't allow them.
