Climate Change Spells Trouble for the Colorado River. But There’s Still Hope

One of the best road trips I’ve ever taken was a sightseeing tour of the Colorado River, where it straddles the California-Arizona state line. I stood at the edge of Imperial Dam near the Mexican border, which diverts water to the farm fields of the Imperial Valley, then drove north to Cibola National Wildlife Refuge, home to lots of birds. I walked along the river in Laughlin, Nev., where there’s a hotel called the Colorado Belle that looks like a boat, and in Needles, Calif., where Snoopy’s brother Spike lives.
