The second largest Continent in the world, Africa has the largest Desert in the world. The Sahara Desert. Apart from which the Namib Desert and the Kalahari are the major ones covering the majority of the continent. Home for the highest sand dunes is the Namib Desert of Namibia. Not the largest of the three but the oldest of them all is this Namib Desert. Dating back to about 80 million years ago, this desert has always had arid and semi-arid conditions.
Two Geologists from the West Virginia University of the United States named Graham Andrews and Sarah Brown. went to the country of Namibia on a field trip. They visited the place to study the rocks of the land which were the typical volcanic rocks.
The desert dominated country of Namibia has given the two a new avenue and led to a new discovery. The two being Geologists came across a peculiar land formation that was not usual to a desert. The desert was flat with sand but had hundreds of long and very steep hills in it.
Upon looking and closely observing this land formation they have realised that these were formed by Drumlins. A feature of the land that usually forms a hill in the places that were once used to be covered in glaciers. These Drumlins were not normal to a desert but are an abnormal feature to it.
One of the geologists, Andrews says, " We quickly realized what we were looking at because we both grew up in areas of the world that had been under glaciers, me in Northern Ireland and Sarah in northern Illinois. It's not like anything we see in West Virginia where we're used to flat-surfaced areas and then gorges and steep-sided valleys down into hollows".
The two have returned home to their university for further study about the Drumlins of Namibian Desert. To their shock, this topic was never studied before at all. " The last rocks we were shown on the trip are from a time period when southern Africa was covered by ice. People obviously knew that part of the world had been covered in ice at one time, but no one had ever mentioned anything about how the drumlins formed or that they were even there at all".
This discovery of their's is the first initial one about Namibian Drumlins and it is a pioneering study towards undiscovered and ever-surprising Earth.
