A vast land of canyons and mountains, the Colorado Plateau is the heart of the American West. Reaching 130,000 square miles along the Colorado River in Arizona, Utah, Colorado, and New Mexico, it’s an iconic landscape filled with unique wildlife and ancient cultures. The Grand Canyon Trust is grounded in this place, working tirelessly since 1985 to protect the air, water, and wildlife of its slickrock canyons, fragile deserts, and forested mesas.
