TERRESTRIAL CHICKEN POX
Many mysteries abound in Africa; many of them
are unexplainable even with science advancement and technological greatness.
Mysteries like ghost attack,
reincarnation, witchcraft, nightmares, e.t.c. have been explained in many ways
but the truth is that not one of the explanations is right.
One of the amazing mystery is an
unbelievable landscape in Namib Desert, what made it more amazing is the fact
that is it physical that is you can see it, touch it, and feel it.
In an
area of about 2,000-kilometer swath along the western edge of the Namib Desert
in southwestern Africa, patches of barren, sandy soil three meters in diameter
dot the landscape.
Each patch is girded with a ring of tall
grass. To some visitors the rings look like terrestrial chicken pox or splash
marks made by giant raindrops.
Local tradition has it that these
circles possess magical powers. Some tribes believe that each circle surrounds
the grave of a bushman who died in one of the many conflicts between Bushmen
and colonialists over the centuries.
The local assertion is more
generally accepted within the local areas and not accepted in science circle.
Scientists too have long sought to
explain the rings. In 1978, assuming that over time the circles would shift position;
researchers marked the centers of some with metal stakes. Twenty-two years
later, the circles had not moved.
There have been abundant theories
on the origin of the circles, including termite activity, poisoning from toxic
indigenous plants, contamination from radioactive minerals and even ostrich
dust baths. These theories were tested one after the other and they were all
disproved one after the other in an overwhelming way.
Perhaps significantly, the
researchers did find that grass withered when planted in soil taken from the
grassy rings, confirming that there is a difference between the soils in the
two areas.
Although initial soil testing failed to
provide any explanation, Van Rooyen hopes that analysis using a mass
spectrometer will turn up further information.
She wonders if there are toxic
elements in the soil of the circles. But even if we find them, how they came to
be there is the next problem. For now, then, the circles remain one of the
earth’s many fascinating mysteries.
