COVER EXPLANATION.—Variably thick aeolian cross sets of the Jurassic Page Sandstone, Arizona, USA. These cross sets are composed of steeply dipping grainflow and wind-ripple strata, and can transition into shallowly dipping wind-ripple strata near the base. The variability in thickness is a product of the migration rate of the dunes, aggradation rate of the bed, and variability in dune scour depths (see Cardenas et al. and Swanson et at al., this issue).
