Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
Classic San Andreas Fault field site on Carrizo Plain National Monument: an intermittent creek right-laterally offset ~130 m by repeated earthquakes, with a short BLM self-guided interpretive trail and parking area. One of the clearest on-land illustrations of transform-fault offset in California — a staple of geology field trips.
