We went deep into the heart of Arizona to see the earth and the sky display their magnificence. After the last of the retreats of our summer tour, Adam and I drove for four days back to Milwaukee. Our first stop was one of the seven Natural Wonders of the World, the Grand Canyon – an impressive and inspiring landscape, overwhelming our senses with its immense size and beauty. As our visit guide explained, almost two billion years of our planet’s geological history have been exposed as the Colorado River and the wind cut through layer after layer of rock. This erosion resulted in combinations of spectacular forms and delightful geologic colours like every shade of red, citron, buff, russet, and pink. In its depths, the canyon is deep red, and at times brown or violet.
