Imagine seeing the varied landscapes of the Earth as they used to look throughout hundreds of millions of years of earth history. Tropical seas lap on the shores of an Arizona beach. Immense sand dunes shift and swirl in Sahara-like deserts in Utah and New Mexico. Ancient rivers spill from a mountain range in Colorado that was a precursor to the modern Rockies. Such flights of geologic fancy are now tangible through the thought-provoking and beautiful paleogeographic maps, reminiscent of the maps in the world atlases we all paged through as children, of Ancient Landscapes of the Colorado Plateau.
