**6. Conclusions**


**Supplementary Materials:** The following video is available online at http://www.mdpi.com/2077-1312/7/6/193/s1, Video Hurricane Odile at San Basilio.mov.

**Author Contributions:** Initial field reconnaissance was conducted by M.E.J. and J.L.-V. in March 2017 with a follow-up visit by J.L.-V. in March 2018 paying close attention to patterns of natural weathering in the rhyolitic basement rocks exposed on the headland at Ensenada Almeja. Fieldwork resulting in collection of shape and size data at the Almeja CBB was carried out in May 2019 by M.E.J. and E.M.J. 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.

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

**Acknowledgments:** Foremost, we are indebted to Norm Christy, part-time resident of Loreto, for his invaluable assistance with logistics during our 2019 visit and for launching his DJI Phantom-2 drone to provide aerial photos of the Ensenada Almeja CBB. Eric Stevens provided critical insight with his video of storm action at San Basilio during Hurricane Odile. Special thanks are due to Tom Woodard in Loreto for arranging our stay at the Spanish Contessa's house at the conclusion of the project. M.E.J. is grateful to Jay Racela (Environmental Lab, Williams College) for help with the experimental calculation of density for the banded rhyolite sample from Ensenada Almeja. Reviews of an earlier manuscript for which the authors are most grateful were provided by two anonymous readers, as well as by Dmitry A. Ruban (Geology and Geography Faculty, Southern Federal University, Russia).

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