Happy Friday, good people!
We close out the workweek with a fold, and today it comes to us from Larry O’Hanlon, who manages the AGU Blogosphere.
Larry writes that he was recently in California, and…
I noticed a little fold in a sea cliff at Calafia State Beach in San Clemente. I barely managed to snap a few pictures before being pulled away by the kids. Looks like soft sediment deformation of beach sands? As it is about 100 m from the surf and maybe less than 10 m above sea level, I’m guessing this is a fairly young deposit exposed by uplift.

I agree that this looks like a soft sediment slump fold.
Thanks for thinking of the Friday fold when you were traveling, Larry! I hope all readers of the blog will consider snapping some fold photos when they see them during their global peregrinations…
