In 1928 astronomer Edwin Hubble came to the Grand Canyon to test it as a site for the world's greatest observatory. In the 1960s the Apollo astronauts hiked into the canyon to learn geology in preparation for lunar explorations. Famous writers and poets have looked to the canyon to find the meanings of nature and God. Dreamers turned a 1909 newspaper hoax into an elaborate myth about ancient Egyptian tombs in the canyon. Canyon of Dreams tells these and other stories.
