Making bird's eye view of the Colorado River from the source to the mouth with Google Earth because wanted to know and seeing it on a 4K display, I was very interested with its unusual stream, especially the magnificent scenery in Grand Canyon National Park and in contrast in the last disappearing water due to the usage for a lifeline of Los Angeles, agricultures and industries. This river tells us the history of the Earth, the history of humankind, and more. Want to raft down it.
