’Coloured bands in Navajo Sandstone.’
Navajo Sandstone, seen here in The Wave (Vermilion Cliffs Wilderness) is composed primarily of wind-blown sand from a vast ancient desert. Minerals of iron oxide, deposited by groundwater after the accumulation of the sand, have created red, orange and yellow bands. Photo Paul Smit.
