Researcher Excavate An Ice Age In The African Desert


In the course of a trip to Namibia to examine volcanic rocks yielded an unanticipated discovery by West Virginia University geologists Graham Andrews and Sarah Brown. While traversing the desert country in southern Africa, they chanced upon a strange land formation, flat desert dispersed with innumerable long steep hills. They swiftly perceived the craggy land formation was framed by drumlins, a kind of hill frequently found in places once engulfed in glacier, an atypical feature for desert landscape.

Andrews, an assistant professor of geology said that they swiftly acknowledged what they were observing because they were raised up in the regions of the world that had been residing under glaciers. It is quite different than what we observe in West Virginia where flat areas are predominant and then gorges and steep-sided valleys down into hollows.

Succeeding the trip and on arriving back home, Andrews commenced researching the inception of the Namibian drumlins, only to assimilate that they have never been considered. Andrews further appended that the ultimate rocks that have been displayed on the trip belong to the era when southern Africa was covered by ice.

People patently acknowledged that part of the world had been engulfed in ice at a time but nobody had ever divulged anything about how the drumlins formed or that they existed in the first place. Andrews joined WVU geology senior Andy McGrady to utilize morphometrics, or measurements of shapes to regulate if the drumlins displayed any motifs that would contemplate consistent behaviorsĀ as the ice carved them.
