In 2012, a satellite image on Google Maps sparked a heated discussion on the Internet about a hill resembling a human lip in the Darfur region of western Sudan. Although little is known about this peculiar landmark, researchers have recently speculated about its formation.

According to LiveScience, the mysterious hill, which has no official name, is about 900 meters long and 350 meters wide at its widest point, and is about 95 kilometers east of the Sudan-Chad border. The coordinates on Google Maps are 12°22’13.3″N 23°19’20.2″E, which is labeled as the “Lip of Nature” and classified as a campsite.
Since the satellite imagery was revealed, the landscape has continued to spark discussion. Based on the available geological analysis, experts have made preliminary speculations about the formation mechanism of the hills.
Josh Roering, an expert in geomorphology at the University of Oregon, noted, “I observed a narrow, exposed rock strip running through the middle of the terrain. “There appears to be a dike in the center of the hill, a rock that is difficult to erode and stands out because it weathers at a slower rate than the surrounding strata.
A, also known as a rock wall, is a geological unconformity intrusive rock mass that cuts through strata, usually formed by volcanic activity or plate movements, and may also be due to sedimentary processes. “The less erosive-resistant surrounding rock formations form a sloping terrain on both sides, while the more erosion-resistant rock formations in the center determine the size of the landform,” Rollin explains. However, he also stressed that more data is needed to verify the current speculation due to the lack of a close survey of the stratigraphy.
