This week on Unbottled, we’re paying tribute to the Colorado River – named America’s most endangered river in 2012. Each day, you’ll have an opportunity to learn about this important water source through a series from National Geographic. And you’ll also have a chance to help restore 1,000 gallons to the Colorado River by taking the free pledge. Find out more about Change the Course here and check out our second blog of the series below.
