Plane travel is pain travel; but the view (not possible from the airliners) is unique and, as Collier demonstrates, exquisitely lovely, instructive and painless. He has shot the mountains feeding the system, follows the Green, then the Colorado with tributary digressions (San Juan, &c.). The photos are clear as gin; colors are truer than reality, at least during the many days when the coal plants envenom the air. Five experts have joined Collier in textual descriptions of river, rock, climate & biota. Buy this book, cherish it; but don't visit (the present small crowds--now being swollen by the Grand Staircase-Escalante park designation--are, already, excessive).
