Overview
The Cristianitos Fault is a major earthquake fault line located less than one mile from the San Onofre nuclear power plant. This hike takes you on a 3.8 mile loop through San Onofre State Beach to the site of the fault line. Along the way, you’ll see the Monterey Formation , which holds most of the oil and gas deposits known in the LA basin and off the coast, as well as the abrupt end of the San Mateo formation at the fault line. It’s a hike and a geology lesson rolled into one!
