Aloba Arch, Natural stone arch in Ennedi Region, Chad.
Aloba Arch is a natural stone formation in the northeastern part of Chad, created by natural geological processes over thousands of years. The structure shows two distinct erosion patterns: water carved the lower section while wind shaped the upper portion.
This formation developed over millions of years through natural erosion processes in the Sahara region. Scientists only documented its precise measurements in the early 2000s using modern surveying techniques.
The arch stands as a geological monument in the Sahara Desert, drawing researchers and photographers who document its exceptional dimensions.
Reaching this site requires a desert journey from the nearest settlement, as the location is remote and isolated. Travelers should go with someone who knows the area well and bring plenty of water and supplies.
The formation bears traces of ancient human presence through rock carvings and pigment marks at its base. These markings suggest the area has been visited or inhabited by people for thousands of years.
