u.l. printed: THE GRAND CANYON is a trough 6000 to \ 7000 feet deep, ten to twenty milies wide, hundreds \ of miles long, people with hundreds of peaks taller \ than any mountain east of the Rockies, and all \ ablaze with such color as no Eastern or European \ landscape ever knew. And as you sit on the brink \ the Dive Scene-Shifter gives you a new canyon \ every hour; with each degree of the sun's course the great countersunk mountains fade away and new \ ones are carved by the westering shadows. The \ Canyon is not only the hugest but the most varied \ example on earth of one of the chief factors of earth \ building - erosion.
