Red Cliffs National Conservation Area in Utah protects a unique transition zone – the meeting of the Colorado Plateau, Great Basin Desert and Mojave Desert. Where these distinct landscapes overlap, unusual plants and animals have evolved, including flowers like the dwarf bearclaw poppy and Shivwits milk-vetch that grow nowhere else on earth. Explore the area’s flora, wildlife and spectacular desert scenery with more than 130 miles of hiking and mountain biking trails. Photo by Bob Wick.
