Combo #FieldPhotoFriday and #faultfriday - a surface of one of the strands of the Soda-Avawatz fault zone in the eastern Soda Mountains north of Baker, CA. The striations show almost perfectly horizontal right-lateral strike slip motion. The fault cuts a probable #Pliocene alluvial deposit and is buried by a middle #Pleistocene alluvial fan deposit. This is one of several fault systems cutting across the Mojave Desert that is related to Pacific-North American plate boundary slip.
