Prospect Dam is a former lava dam in the Grand Canyon of Arizona, United States. It was the oldest and tallest of several former lava dams in the Grand Canyon.[1] It was formed about 1.2 million years ago as lava flowed down the walls of the Grand Canyon, and temporarily stopped the flow of the Colorado River.[2]
