Cover: Lowest antidune bed at Canyon Lake Gorge. Several lunate wave crests occur with steeper lee sides facing west, therefore flow was towards the west (e.g., Leeder, 1982). The strike of wave crests is roughly 10° so paleocurrent moved at +/- 280°. Other more mound-shaped antidunes (lower left and upper part of the photograph) are slightly asymmetrical with a longer, gentler stoss side to the east and steeper lee side to the west. Distance between wave crests varies between 30–40 cm with wave heights of 4–5 cm. For more information, please see Sigler et al. paper herein.
