Great Natural Monuments - Grand Canyon

Great Natural Monuments - Grand Canyon

Passionate geologists Karl Karlstrom and Laura Crossey take a fascinating journey along the Colorado River to discover the natural monument that is still far from having revealed all its secrets. They cross the wildest rapids brought about by the clash between the Colorado River and the most ancient rocks of the Grand Canyon. And they solve the enigma of its formation, debated for 150 years.
