The Colorado River stretches 1,450 miles and meanders through five states and two countries; at one time, more water flowed from the Colorado into the sea per second than tumbles over Niagara Falls. Five million years ago, it raged through Arizona and created one of the Seven Natural Wonders of the World: The Grand Canyon. In 1869 John Wesley Powell, the one-armed Civil War veteran and scientist, led an expedition down the virtually unknown Colorado. The journey was perilous; only six of the ten men who started down the Green River (a tributary of the Colorado) made it to the mouth of the Colorado three months later. Rapids, waterfalls, and cliffs created a river that was nearly impossible to navigate. Now, in 2017, the portion at the end of the river flowing through Mexico can generously be called a “stream,” and more realistically be called a “trickle.” Since 1990, there has rarely ever been a time where the water reached the Gulf of California.
