Sandy, laterally accreting channelform incised into floodplain/shoreline coals in the Cretaceous Book Cliffs of Utah; this famous outcrop is right on I-70, and has probably been responsible for a number of insurance claims among geologists, I reckon!
Trace fossils on deltaic sandstone bedding surface, from the Cretaceous of the Western Interior, Book Cliffs, Utah.
Turbidite with a partial "Bouma Sequence" (A, B, and C divisions, I reckon), representing the deposit of a turbidity current. From the Cretaceous Book Cliffs, Utah.
