Stop Grand Canyon Tram

Since 2009, a Phoenix-based developer has been pushing the Navajo Nation to approve the Grand Canyon Escalade, a proposed development located above the sacred confluence of the Colorado and Little Colorado rivers. This development includes a 1.4-mile tramway that would shuttle up to 10,000 visitors a day to the bottom of the Grand Canyon, elevated walkway and riverside amphitheater, as well as a hotel, restaurant, and RV center above the rim.
