The lush green slopes of the Rocky Mountains are the source of almost all the water that keeps the American Southwest alive. The winter snowpack slowly melts over the year, guaranteeing a steady supply of water for its many rivers of which the Colorado is the most important. If temperatures rise through climate change, there may not be any snow in a few decades. The winter precipitation will immediately run off, leaving the summers dry and hot without enough water.

Images can say more than a thousand words. And sometimes two images together can convey the whole message. Here a few double images that illustrate the conflict between the different uses of Colorado River water. Other combinations just work nicely together visually.
