Aloba Arch is a natural arch located in Chad. Large natural arches are somewhat rare outside the southern and western regions of China and the Colorado Plateau of the southwest United States. Chad's Ennedi Plateau, located within the Sahara Desert in the northeast part of the country, has a geology similar to the Colorado Plateau and has produced a number of natural arches and similar landforms, although only Aloba can claim to be on the top ten list of longest arches in the world. Xianren Bridge (Fairy Bridge) in China has a span of which is the longest discovered and measured span to date. Perhaps more notable than the span, however, is the height of the arch. At tall, it towers over the more famous Rainbow Bridge and is one of the tallest known arches in the world.
