Above Yosemite. "What John Muir would have given to see Yosemite from above!" exclaims Harold Gilliam in his book-length test to this photographic tone-poem. Indeed, not even mountain climbers or hang-glider pilots can view a fraction of this most treasured National Park. Teddy Roosevelt call it America's mightiest beauty, and the Sierra Club was born to watch over it. This handsome volume is an enduring record of nature's masterpiece, the finest sculpture of Ice Age.
