This style of crossbedding is traditionally interpreted as reflecting stream deposition, and hence a continental (rather than marine) environment.

The de Chelly (de shay) sandstone is a unit with large-scale crossbedding, inferred to be of dune origin, like the Navajo Sandstone of Zion and Glen Canyon. It's considerably older, though, being Permian, some 150 million years or so before the late Jurassic. It forms both Canyon de Chelly and the buttes in Monument Valley. It's correlative with the Coconino Sandstone of the Grand Canyon. On the trail to White House ruin.

Outcrops of Aztec Sandstone showing large-scale crossbedding. Red Rock Canyon Recreation Area, southern Nevada, USA. The Aztec is correlative with the Navajo Sandstone of Utah (Zion Canyon) and Arizona (Glen Canyon), but has a different name here for historical reasons.
