Sandstone Pockets

Sometimes the Navajo Sandstone is weathered in amazing formations. When nature’s forces of wind, rain, freeze and thaw have so many millions of years to effect these surfaces even the smallest scale action is amplified.

Here pockets have opened in the sandstone along the shores of Lake Powell. Softer materials have been washed or blown away in favor of the harder minerals. The oranges, pinks, reds and purples of the sandstone are caused by a mix of hematite, goethite, and limonite which has seeped within the quartz sand. The whiter material, often found at the tops of the formations, have had most of these iron oxides leach into the deeper layers, revealing mostly silica.

Navajo Sandstone, Waves of Rock and Water

One of the most magnificent sights of Lake Powell and the Glen Canyon National Recreation Area is the juxtaposition of the waves of Colorado River water and the frozen waves of Navajo Sandstone. Both exhibiting relaxing, fluid motion, but the sandstone echoing waves of sandy beaches and earthen deposits of about 200 million years ago, now frozen in time.
