Such erosion surfaces form during deflationary episodes or during periods of erg stabilization or contraction. They are called "super surfaces" and can be useful for stratigraphic correlation because of their regional extent.The Permian Cedar Mesa Sandstone and Cutler Formation contain a type off super surface (herein termed "flood surfaces"), ∼10-400+ km2. Flood surfaces form as a result of fluvial floods into active dune seas. The surfaces may expand through nonclimbing migration of eolian dunes but do not imply long hiatuses in eolian deposition as do other types of super surfaces. Cutler and Cedar Mesa flood surfaces are overlain by shales and sandstones which thicken laterally and merge with fluvial channel-fill deposits. Flooding of active dune fields in the Cedar Mesa Sandstone is suggested by intertonguing of eolian dune and fluvial deposits. Flood surfaces can easily be mistaken for deflationary super surfaces but are distinguished by evidence of dune migration coincident with flood events and by an increase in the number of surfaces adjacent to associated aqueous deposits.
