04-Apr-2010 -- On my visit to Botswana (en route to Namibia) over the period 2 April to 6 April, I planned to visit two undocumented Confluences at 20S 22E, and 20S 21E.
First Confluence to be attempted was that at 20S 22E, on 4 April 2010.
The Confluence lies about 1.8 km off the northern track to Drotsky's Caves in Western Botswana.
After visiting Lake Ngami, which had water for the first time in over 20 years, the traveling party headed north on the main surfaced road which skirts the west of the Okavango Delta. We then turned off westwards onto the narrow, sandy and bumpy track that lead to the caves.
We easily found the turning onto the northern track, but after traveling this track for a few kilometers, found further progress impossible for the Land Rovers, because the tracks were completely overgrown. Trees had fallen over the tracks, necessitating undergrowth slashing to get through.
After an hour of this, with minimal progress, we reached 20.08777°S 22.07418°E (12.5 km from the Confluence). At this point we decided to call this one off as an "Incomplete".
The Confluence may be accessible from the West, but I will leave this to another intrepid adventurer who has more time.
Continued at 20S 21E.
