Source to Sea: Down America's Most Endangered River in Three Minutes (VIDEO)

American Rivers, an advocacy organization, announced their 2013 report of the country's 10 most endangered rivers on Wednesday. The Colorado River is at the top of the list as recreation-based economies, wildlife, and world-renowned canyons continue to be threatened by what American Rivers is calling "outdated water management" policies in the region.

The fact that the Colorado is endangered is nothing new; it hasn't reached the sea consistently since the 1960s. But as the number of people who rely on Colorado River water continues to grow, it is being placed under more and more strain.

Recently, Will Stauffer-Norris and I paddled and walked for over 1,700 miles, following the Colorado from source to sea. Watch a 3-minute time lapse of the journey below to see how this iconic river begins -- and where it eventually ends up.
