The River That Just Disappears

Rivers are the water paths that rain and snow follow from higher elevations to lower elevations until they reach the ocean. The Colorado River, on the other hand, flows from the Rocky Mountains in Colorado through several states and then just disappears. Oh, it used to flow into the Pacific Ocean, but that was before people moved to the western US and wanted to live there a grow crops despite the fact that it's a desert. 

Half as Interesting takes us on a tour of the Colorado River and what happens to all that pristine snow melt along the way. The video is eight minutes long; the rest is an ad.
