The Late Triassic-age Chinle Formation, marked at its base by the light-colored, gravelly Shinarump Conglomerate Member, overlies red beds of the Early Triassic Moenkopi Formation. Late Triassic rocks record dramatic drying of Utah’s landscape, as drab gray floodplain deposits in the lower Chinle give way to more oxidized, reddish sand dune deposits of the cliff-forming Wingate Sandstone.

POTD January 6, 2015: Colorado River, Grand County, Utah

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.
