The Sandstone Top of the Canyon

The Sandstone Top of the Canyon

The Sandstone Top of the Canyon

This is not the easiest thing to do—especially in a 100 degree heat—but it’s worth it. Every foot I descend takes me further back in time. ”The first layer you come to in this part of the Canyon is this pinkish rock I’m hanging next to right now. It’s called the Esplanade Layer and like all the rocks in the Grand Canyon, it’s an ancient landscape frozen in time.”
