A MYSTERIOUS ‘shifting sand dune,’ which moves like a ‘walking mountain,’ in Ngorongoro Crater, and perhaps fit to contest in the list of ‘Wonders of the World,’ is yet to be fully marketed, it has been learnt.
The declaration was made by Olduvai Site
Museum Deputy Conservator Mr John Peter Pareso in the Ngorongoro
Conservation Area Authority (NCAA) recently, stressing that the strange
“mobile mound” should be ranked high among the ‘wonders of the world,’
though little is still known about it, because it was only recently that
it was included in the NCAA map.
“Mountains do not normally move, but
this mysterious “hill of sand” has been traveling at a speed of 20
meters per year, and now NCAA mulls rebranding and marketing it afresh,”
he pointed out.
The still ‘nameless mountain,’ as high
as more than 10 meters, with a width measuring 100 meters, has covered
slightly above one kilometre since its movement was detected and
documented in the early 1960s.
He said the shifting sand which is wind
propelled, though still requires special research, in 2001 headed
towards a river and people feared it could dissolve in the water mass,
only to suddenly change direction miraculously.
“The ‘moving earth mound’ has been
changing shapes like in 1991 when its height increased, and again ten
years before that in 1981, it had split into two segments with the
smaller one heading in a different direction.
“And in 2011, there was a slight change
in its composure, when it seemed to have grown more compact exceeding
its usual 10 meters’ height. And its normal 100-meter width seemed to
have shrunk down to 50 meters wide,” Mr Pareso said.
Experts say the dark-sand surfaced hill
was formed over 3,000 years ago from a massive eruption at ‘Oldonyo
L’engai’ in an active volcano, being Tanzania’s third highest mountain
located on the leeward of Ngorongoro Conservation Area.
The conservator further said records
show that a cone from ‘L’engai’ shot off and landed at Osukunua, an area
within NCAA from where it started its slow movement in the South-West
direction for hundreds of years, before it changed its bearings to
North- West in 2001.
Traveling south, the mountain has
covered both the Salei and Angata plains, gone past Naibor Hills, and is
now within the Oldoinyo-Gol plains heading towards the so-called
‘Ngorongoro endless plains,’ he added.
He hinted that the first beacon to
record the mountain’s movement was placed there in 1969, after which
others followed in 1976, 1981, 1985, 1990, 1995, 1998 and 2003 in that
order.
“The latest one was placed in December 2011 during the country’s 50th Anniversary of Independence,” he further said.
