“We pray for the rains to come, for the snow to fall, for moisture in the earth. Not just for the Hopi, but for everybody. For every living thing that’s out there.” – Howard Dennis, Hopi Elder The Green and Colorado river systems form the backbone of the American West. Once spanning a 1,450-mile journey from the Rocky Mountains to the Gulf of California, today, none of the sediment-rich water reaches the Pacific Ocean. Instead, its water lies stymied in reservoirs and siphoned off to feed and nurture 40 million people from Salt Lake to Los Angeles. One hundred and fifty years after John Wesley Powell’s historic descent of the Green and Colorado rivers, an unlikely crew of scientists, artists, educators, and river lovers repeated his journey on a trip that was simultaneously a celebration of modern river life and a critical look at how we interpret the Colorado River’s history and use its waters. As the demand we place on the water of the Colorado continues to exceed its supply, we are forced to face uncomfortable truths about decisions made in our past. And we are reminded that the way we think about water—and all those dependent upon it—needs to shift if we want things to change for our future. “Water is a life force for all of us. It has a spiritual and physical being to it that deserves respect. It’s not something that you take for granted.” – Lyle Balenquah, Hopi archaeologist
