Wrinkled Valley Surface

The surface of Cottonball Marsh had a wide array of textures from smooth silts and clays to heavily upturned plates formed by shrink and swell of the clays to areas with numerous shallow pits with salt crusts around them.

 

This type of texture was present in areas near the little streams. The wrinkled look is probably due to the presence of clays that shrink when drying.
