In this masterful tour de force of nature writing, Kenneth Brown explores one of the most awe-inspiring regions on earth -- the Four Corners of Colorado, Utah, Arizona and New Mexico. Weaving together its geological, ecological and human histories, he presents a unique portrait of this ruggedly beautiful landscape that goes beyond mere description to give readers a true sense of the land in all its richness. Here are rock croppings that are 2 billion years old and broad desert valleys where rivers of lava cooled to form floors of solid rock. Here ancient hunter-gatherers stalked the woolly mammoth, four-story pueblos were carved by the Anasazi from sheer stone cliffs and an ancient midnight Holy Week ceremony is still practiced in a modern Spanish village. <P> Providing a fresh perspective on a region currently enjoying an upwelling of interest, <I>Four Corners</I> is a fascinating study of one of the world's great wonders -- compelling reading for all science, nature, anthropology and travel aficionados.
