This subspecies is unique to the Grand Canyon on either side of the Colorado River in Northwestern Arizona. They primarily use riparian ecosystems in the canyon floor, but can also be found in talus (exposed rocky slopes) and mesquite-scrubland.
Grand Canyon Rattlesnakes are generalist predators, taking any available prey (usually rodents and lizards).
