The southern portion of Lake Powell in Glen Canyon National Recreation Area is featured in this southwest-looking, low-oblique photograph. Rugged, snow-covered Navajo Mountain lies southeast of Lake Powell, which covers 252 square miles (653 square kilometers) and is used primarily for recreation and irrigation. Apparent are the Paria Plateau escarpment in northern Arizona (upper right) and the snow-covered Kaiparowits Plateau discernible to its north-northeast.
