Hi evrybody. Thanks for your interest. I will check the german sites and see if these caves have been visited without locals noticing. The caves are in 2 places in the Kaokoland, northwestern Namibia. It's mountainous terrain. First one is about 50 km southwest of Opuwo and about 40 mn walk from the next village. The villagers tell me that there have been only 2 europeans who came and only had a look at the entrance, and that was many years ago. They assured me nobody never went inside. There's no way to prove it, but I believe them. The entrance looks quite dangerous because of a steep cone going down and the actual entrance looking like a big dark hole. Locals are very much afraid of any cave. The other 2 caves seem to have a possible link since they are about 3 km apart. They are about 100 km southwest of Opuwo and it takes one day driving very bad tracks, and 2 hours hiking to get to each. I saw one entrance from a viewpoint about 2 km away. Looks quite large, too, but because of time, I couldn't get any closer. The other one is on top of a mountain. I saw it while flying over in a cessna and took a picture. Again, some locals know them but don't care the least, and they assured me no one has ever gone inside. According to them, the last cave is very steep, almost vertical and about 10m wide at the entrance. There are more caves in the region, some of them explored, other only partially. One of them was investigated by the south african army and was found to be full of toxic gaz. There are no running rivers in the whole region and only tiny springs.
I've googled for the South Africa Speleo Society and found nothing. Can you help?
I do have 2 pictures. How can I add them to the posting? I have to try to get good pics. Mine are almost useless. Just clues.
I will also investigate the german website about caving in Namibia, but I have to admit I tend to trust the old local Himbas assuring me that no-one has ever tried to descend in these caves.
