Hadjer-el-Hamis, also known as the 'Elephant Rocks,' is a group of five prominent volcanic plugs rising abruptly from the plains north of N'Djamena. Located near Lake Chad and the Chari River, these geological formations are primarily composed of rhyolite, an acidic volcanic rock. The rocks are the remains of ancient volcanic vents whose surrounding softer rock has eroded away over millions of years. For the local population, the rocks hold significant cultural and religious importance, serving as sites for traditional ceremonies. The highest peak rises about 200 meters above the surrounding savanna, offering expansive views across the Lake Chad basin. Geologically, they belong to a chain of volcanic activity associated with regional rift systems. The distinct shape of the rocks resembles a group of elephants from a distance, giving them their popular name. During the rainy season, the rocks are surrounded by lush green grasslands, contrasting sharply with the reddish rock. The area is a key destination for geological research and local tourism.
