Aloba Arch Torohi, Chad Last Updated: 04/05/2024 | |
Aloba Arch is a natural arch located in Chad, specifically on the Ennedi Plateau within the Sahara Desert in the northeast part of the country near Libya and Sudan. The arch is considered to be the 8th longest known natural arch, with a span of approximately 250 feet (76.2 m) and a height of 394 feet (120.1 m), making it one of the tallest known arches in the world. | |
Aloba Arch is unique because it is the only one in the top ten list of longest arches not located in either the United States or China but in the remote wilderness of Chad. The arch is part of a region with similar geology to the Colorado Plateau, which has produced a number of natural arches and similar landforms. Despite its grandeur, visiting the Aloba Arch can be quite challenging due to its remote location and the harsh environment surrounding it. The best time to visit is between November and February when the temperatures are milder, but specialized vehicles and experienced guides familiar with the area are necessary for the journey. The Aloba Arch began as sedimentary rock layers deposited over time, which changed due to pressure and movement beneath the Earth's crust. Over millions of years, the region experienced uplift and subsidence, leading to extensive rock formations and deep canyons. The arch appeared as softer rock layers eroded more quickly than the harder layers above, resulting in a bridge-like structure that has withstood the test of time. The sedimentary layers reveal the region's geological history, with each stratum bearing witness to different epochs in Earth's evolution. |
