Sunset on Gooseberry Mesa shines golden light on cliffs of Triassic-age Shinarump Conglomerate and the underlying slope-forming Moenkopi Formation. White cliffs and peaks in the distance are thrones and temples of Zion National Park, formed of Jurassic-age Navajo Sandstone. Gooseberry Mesa, Washington County, Utah Photographer: J.

Late-winter ice still clings to the Colorado River near Big Bend, north of Moab. Boulders of Jurassic-age Wingate Sandstone and Triassic-age Chinle Formation line the banks of the river, eroded from the cliffs and ledges cut by the river as it has incised its channel over millions of years.

Permian- and Triassic-age sedimentary rocks color the shorelines of dam-impounded Lake Powell near the confluence of the Colorado and Dirty Devil Rivers. Although the lake water has submerged numerous relicts of ancient animal (including human) and plant life, traces of prehistoric life can still be found along the lake shores and in some tributaries.
