Welcome to Petrolia, California, a site of historical significance as the birthplace of California’s oil industry. This serene location in the Mattole Valley, part of the Lost Coast region, is where the first successful oil wells in California were drilled. In June 1865, the Union Mattole Oil Company began extracting oil, marking the beginning of California’s journey into the oil industry. The crude oil was transported to San Francisco for refining, establishing a new economic activity that would become a significant part of California’s industrial landscape.
The town of Petrolia itself is small and isolated, contributing to its untouched charm. It is home to a variety of wildlife and natural beauty, with lush forests and the nearby Mattole River enriching the landscape. Historically, the Mattole Valley was inhabited by the Mattole people, who were tragically almost wiped out following the arrival of Western settlers in 1849.
Throughout its history, Petrolia has experienced its share of natural events. It is situated near the Mendocino Triple Junction, where three tectonic plates meet, resulting in frequent seismic activity. In 1992, a magnitude 7.1 earthquake caused significant damage, including a fire that destroyed the Petrolia General Store. Despite these challenges, the resilient community rebuilt, preserving the town’s historical essence.
Today, Petrolia stands as a reminder of California’s early industrial endeavors and its natural beauty. Visitors can still see the remnants of old well heads and experience the untouched wilderness of the Lost Coast. The story of Petrolia is one of discovery, resilience, and the intersection of natural and industrial histories.
