**Author Contributions:** Initial field reconnaissance was conducted by M.E.J. in February 2018, with a follow-up visit by M.E.J. and E.M.J. to collect field data in April 2019. M.E.J. prepared the first draft of this contribution, drafted all figures, and supplied all ground photos. R.G.-F. was responsible for working out the mathematics related to storm hydrodynamics. J L.-V. summarized the literature on basin turbidites in the lower Gulf of California that negates claims regarding tsunami activity in the region. In addition, J.L.-V. contributed input on fault orientations within the study area. Authorship has been limited to those who contributed substantially to the work reported. All authors have read and agreed to the published version of the manuscript.

**Funding:** This research received no external funding.

**Acknowledgments:** Foremost, we are grateful to Norm Christy, part-time resident of Loreto, for his crucial assistance with logistics during our 2019 visit including guidance on overland access to the boulder barriers at Puerto Escondido. Use of a vehicle and two-person kayak was made available for completion of fieldwork. M.E.J. is indebted to Jay Racela (Environmental Lab, Williams College) for help with the experimental calculation of density for the andesite sample from Puerto Escondido. Reviews of an earlier manuscript for which the authors are most grateful were provided by two anonymous readers.

**Conflicts of Interest:** The authors declare no conflict of interest.
