Chobe: Savute, Mababe & Nogatsha (6)

We know from the accounts of early explorers that the Channel was flowing in the 1850s and until about 1880.

At that time, the flow ceased and the Channel remained dry until the mid-1950s, when it inexplicably began to flow again.

Since then, it has "switched" on and off several times.
It is this quixotic pattern that explains the dead trees to be seen in the Channel.

No convincing reason for this paradoxical flow pattern has been proved.
Maybe, the most likely candidates are tectonic instability, which may be tilting surfaces first in one direction and then in another, and the coincidence of high flood levels in both the Chobe River and the Zambezi  - which backs up along the Chobe.

You'll find San rock art at several places within the Gubatsha Hills; national park staff will be able to show you where.
