--- Quote ---The Thalamakane Fault acts as a 150-mile-long natural dam: Here the channels abruptly change direction and join to form one river, the Boteti.

Apskip has merely misunderstood what Dr. Green wrote.

Which is exactly what I pointed out in post #43 above.

--- Quote from: apskip on March 25, 2013, 03:42:18 PM ---The Boteti River runs through Maun and on into the Okavango Delta. On the other side of the Delta, the flows out consolidate from 3 prongs into one Okavango River. I expect that the water skiing was on the Boteti River and not the Okavango River.

Then you would be wrong. :o
Here is the location of the crocodile water skiing: Thamalakane River, 8 miles northeast of Maun

Chateau,
I guess where the Thalamakane flows and when it becomes the Boteti River is open to some differences depending on your source. Here is one I have discovered after additional research on this subject:
Great Places Physical Geography by Dr. Cecil Keen July 2007
2 parallel faults now control the direction in which the Okavango River enters the Kalahari Basin, in an area called the Panhandle. Other faults also direct its exit from the Delta, flowing south into the ocean of sand. As the Okavango flows over the Gomare Fault, a continuation of the Great Rift Valley of east Africa, that runs southwest to northeast, the slope of the land breaks it up into numerous channels, which fan outwards over the Delta. These are blocked by 2 southern faults, the Kunyere and the Thalamakane, which redirect the Delta's myriad channels. The Thalamakane Fault acts as a 150-mile-long natural dam: Here the channels abruptly change direction and join to form one river, the Boteti, which flows eastwards through a break in the fault towards the Makgadikgadi Pan. A small channel, the Nghabe River, continues southwest toward Lake Ngami, serving as both inlet and outlet depending on the strength and direction of the annual floods.
Unfortunately, Dr. Green does not identify precisely where the change from the Thalamakane Fault to the Boteti river happens.
I have also discovered sources which recognize a Thalamakane River (not mentioned at all by Dr. Green). One is tourist literature from the Thalamakane Tourist Resort. It states "This metropolis (Maun) is now spread out along the wide banks of the timeless Thamalakane River. It also shows photos of canoes being poled.

apskip.......you still have two references to Dr Green.......who is he?
apskip:
Dr. Rox,
I have posted #42, #45 and #49. Please read them again carefully. There are no references to Dr. Cecil Green although I did indicate in #49 that I had originally misremembered Dr. Keen as Dr. Green but corrected that immediately. The bottom line is that there is no Dr. Green so please cease and desist badgering me about irrelevancies.

Do we know where the Pitstop is ???? Hope it is overlooking the Okvango Delta!!!!
