Kalahari pans - Salt pans - Types and formation:
Pans
The pans or "panne" (pronounce "punne" in Afrikaans, is a very
characteristic feature of the Kalahari, although the Karoo is reported to
be "the" place to go for pans. On a map there appears to be two distinct
lines of pans, namely between Buitepos and Aranos in Namibia, and again
between Tses and Noenieput, even as far down as halfway to witpan, or the
line between kakamas en Van Zylsrus. I must say, from simple inspection on
a map, and considering the direction of the existing dry rivers as
indicated on the map, I can easily imagine a river flowing from the
Okavango Delta, along the path of these two lines of pans. The experts
have however told me that this theory first expounded by prof Swart and
later given prominence by Michael Main in his book "Kalahari - Life in
Dune and Delta", has been discounted as the levels are not correct. There
are apparently no seismic activity on a scale that could have altered the
lay of the land sufficiently to make even a remote possibility. (Michael,
if you ever read this, please contact me as I would like to get permission
to use a few of your photos.) The lines of pans I refer to above, does not fall on the possible proto-tswana river path as showm by Main.
The origin of the pans are uncertain. What does seem certain, is that
large hordes of animals are attracted to salt deposits in the pans. It
seems fairly obvious to me that a horde of animals trampling the last bit
of remaining water to a powder, could easily, over the aeons, create such
a pan. My personal experience with the fine dust produced on a parade
ground, which, as we say in Afrikaans is "tot stof getrap" "= trampleled
into dust" make this seem likely. This dust, in addition to the higher
salt content in the evaporated water, would certainly make a nice and
impervious bottom to any pan. Besides the well-known "Verneukpan" near
Springbok to the South, and the large Makgadikgadi pans to the far north
east in Botswana, two of the largest pans, namely koppieskraalpan (from
the adjacent eierdop koppies = egg shell koppjes = like broken egg shell)
and Hakskeenpan ("Heel"-pan) are found in the Kalahari.
There are a large number of other pans, many of them with rather rude
names like Skitterypan (on some maps sanitised to Skreipan) of which there
are a small one and a large one. This name tells me (in not too polite
terms) that some-one had a severe bout of diahoerea at these pans. (It is
no longer known who this person was). Many of the names are of Khoi/San
origin. Perhaps the strangest apparent discordance between pronunciation
and spelling, is found in what appears on the map as "Obobogorap". This
name is pronounced "Kiebietjiegora" or in English approximately
"kewbitjegorab". This strange discordance suddenly became clear to me,
when I read an old German book "Aus Namaland and Kalahari' 1907, Jena, by Leonard Schultz.
In a flash, it became clear that the original name had a number of strange
orthographic letters, such as ! and /, and that the map-maker had simply dropped
these funny characters. There are also such old favourites of mine as Kooppan-Suid and
Kooppan-Noord.
The pans have a very flat surface, which makes them ideal for instant
roads, aeroplane landing strips, and land speed record attempts. Nice for
driving lessons too! There is nothing you can run into!)..
In the larger pans, some are up to 20 kilometres from edge to edge, it is
extremely easy to get lost at night. It is presumably because of the
slight depression in the middle, that what one are convinced of is a
straight line route, because you have kept the steering wall absolutely
fixed, always seems to spiral back into the centre of the pan. Numerous
stories of even experienced travellers in this area, who got lost a night
in one or other pan, is told. Fortunately, very few people have actually
died from this cause in the last twenty years or so..
To see haakskeenpan or koppieskraalpan, or Inkbospan full of water, is an
incredible experience - You see this large area of water, and you expect
it to be deep. You start walking towards the centre and it doesn't get
much deeper. Most of these pans are I understand, are less than half a
meter deep at the centre, although I have seen figures of over 3 m as well (even 20 m)!. I have never had the tenacity to keep on walking
for the amount of time it would take to get to the centre, so I
have to trust the word of people who have (knowing those farmers, they
probably drove there in a pick up truck, which puts 3m outside the question, or leaves it as pure guess-work!) .
