The American West: Dramatic Landscapes
In The American West: Dramatic Landscapes, narrator Sir David Attenborough explores the desert of the American West as a 10-month drought is ended by an intense thunderstorm. As millions of tons of water are dumped in under an hour, raging rivers form. Over millions of years, raging waters like these have carved slot canyons and shaped a beautiful landscape. This video is excerpted from BBC’s Planet Earth II, a breathtaking documentary series that highlights the natural wonders of our planet.
