The impressive sandstone formations: buttes, spires, and towers – the geological monuments that gave Monument Valley its name – are the result of centuries and millennia of erosion and uplift. Red sandstone cliffs and spires are predominantly made of Cutler Formation sandstone from the Permian period of around 160 million years ago.

2004-8-1 · A non-creationist interpretation for the Navajo Sandstone. A young-earth creationist interpretation might suggest that: 1) the sands were eroded from the uplifted Appalachians during the Flood, 2) the clastic sediments were transported by continent-crossing currents and 3) the quartz sands were eventually deposited in the area where we presently find the Navajo Sandstone in the south …

2008-5-19 · The outcrops of Navajo Sandstone in southern Utah andnorthern Arizona are composed of large−scale, southeast−dipping a cross−strata (Loope and Rowe 2003). The fullheight of the bedforms that created the distinct, large−scalecross−strata is estimated, from studies of a nearby outcrop ofsimilarly sized cross−strata (Hunter and Rubin 1983), to haverepresented a typical dune height of about 30 m. The presentday weathering profile of the Navajo Sandstone is such thatindividual, potentially track−bearing surfaces are rarely ex−posed (DeBlieux et al. 2006), but at the Coyote Buttes site lo−cated on the Utah−Arizona border, tracks of vertebrates occurin a single, distinct stratigraphic interval up to 10 m thick(Fig. 1). In this area, Loope and Rowe (2003) described evi−dence for three pluvial intervals during Navajo …
