A few times a year, fed by snowmelt and monsoon storms, the normally dry Grand Falls swells into a raging wall of muddy water. The 180-foot seasonal waterfall has become something of a destination for road trippers, van lifers, and influencers in recent years. But for generations, Grand Falls and the Little Colorado River that feeds it have watered livestock, supported medicinal plants, and sustained Native peoples. Grand Falls, called “Adahiilíní” in the Diné (Navajo) language, is located on the Navajo Nation in Arizona. For Herman Cody and his niece Radmilla Cody, it is the place they call home. “We’re all a big family living along that river,” Herman said.
