The American Southwest is world-renown for its colorful and spectacular landscapes like Grand Canyon, Sedona, Monument Valley, the Superstition Mountains, and the Sonoran Desert. But how did these wonders come to exist and what can ordinary rocks tell us about their ancient origins? You’ll be amazed to learn that the Southwest was once the site of warm, tropical beaches; shifting dunes in Sahara-like deserts; coastlines stalked by large dinosaurs; and rivers that once flowed towards the present-day site of the Rocky Mountains. These long-lost and surprising scenes from the past come alive in beautifully designed maps that are stunning and scientifically accurate.
