The essence of the earth's beauty lies in chaos, in the disorder of grasses strewn in a meadow, the blotching of green lichen on a tree trunk. Eliot Porter's photographs of the natural world, spanning thirty-five years and five continents-from an Antarctic ice floe to an American desert to an Icelandic lava field-reveal in mesmerizing ways what scientists are beginning to see for themselves: the patterns, relations, and inter-actions present in nature's disorder and wildness. This is the perfect marriage of image and text-brilliant full-color photographs by the preeminent nature photographer of his generation together with an illuminating essay by the widely praised author of Chaos.
