Arizona photographer Gary Ladd celebrates the different facets of Glen Canyon`s Lake Powell -- both the brimming lake itself and the quiet, trickling side canyon waters -- in this collection of his work. Ninety-six side canyons twist into the main channel of Lake Powell, into what was once the main artery of the Colorado River through Glen Canyon. Each is unique, with names reflecting early explorers` impressions: Cathedral, Music Temple, Forbidding, Forgotten, Labyrinth. Lake travelers today, visiting a vastly altered system of canyons from those first sighted by early river runners, often reflect on environmental questions and consequences surrounding society`s reshaping of the natural world. Lake Powell encompasses only thirteen percent of still largely pristine Glen Canyon National Recreation Area. As visitors increase, so do impacts on the delicate desert ecosystem. Glen Canyon`s Lake Powell now challenges us with a vital task: the wise care of both the lake and its incomparable surroundings.
