FRONTISPIECE: Trail Ridge, a remnant of the rolling upland the forms the roof of the Rockies in Rocky Mountain National Park. Originally formed 5 to 7 million years ago, it has survived despite being broken by faults, uplifted several thousand feet, cut by great canyons, and subjected to the vicissitudes of the Ice Age.
