I used to see this type of erosion in Oklahoma all the time, though this one is in South San Francisco (at the foot of San Bruno Mountain).
I'm not entirely sure of all of the mechanism, but it certainly appears to be water borne. You can almost imagine rivulets of water washing away the spaces between these ribbons of soil. The patterns have always seemed to me to be visually fascinating.
