The strong, pure light of the Southwest often produces a dramatically illuminated landscape when thunderstorms sweep across the region’s deserts, grasslands, and mountains. Here, as a storm clears, two towering yuccas glow in the warm light of the setting sun. In the background, a bright rainbow and tattered clouds hang in the rain-cooled air. This photograph was taken in the high grasslands near Mescal, Cochise County, Arizona.
