Color Kaleidoscope, Grand Staircase-Escalante National Monument, Utah. The amazing hues come from the Chinle Formation, renowned for holding a vast forest of petrified trees, some of them 30 feet in circumference. These super-cool colorful clays also contain Triassic dinosaurs. Sadly, the Chinle is saturated with hydrocarbons and uranium deposits putting this area squarely in the crosshairs of the Trump administration.
