**Aloba Arch** is a [natural arch](/source/Natural_arch) located in [Chad](/source/Chad). Large natural arches are somewhat rare outside the southern and western regions of [China](/source/China) and the [Colorado Plateau](/source/Colorado_Plateau) of the southwest [United States](/source/United_States).[1] Chad's [Ennedi Plateau](/source/Ennedi_Plateau), located within the [Sahara Desert](/source/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.[1]

Aloba Arch's span is considered to be the 8th longest known natural arch, and the longest outside of China and Utah.[1] Due in part to its location as well as being only recently recognized for its size, estimates based on photography yield an approximate span of 250 ft (76.2 m).[2] [Xianren Bridge](/source/Xianren_Bridge) (Fairy Bridge) in China has a span of 400 ft (121.9 m) which is the longest discovered and measured span to date.[3] Perhaps more notable than the span, however, is the height of the arch. At 394 ft (120.1 m) tall, it towers over the more famous [Rainbow Bridge](/source/Rainbow_Bridge_National_Monument) and is one of the tallest known arches in the world.[4]
