Climbing-ripple cross-laminae and horizontal laminae are abundant in the upper portion of many channel bodies, with some partially preserved antidune bedforms (Allen et al.
5), which may represent a transitional antidune, and by sandy wings, which record periods of maximum discharge when flow topped levees (Friend et al.
1975, diagram) would be plane bed during the maximum ebb and antidunes during the maximum flood, both corresponding with a higher flow regime than the indicated by the observed bedforms.
