It’s about time to wrap up this expedition and leave Swaziland for this time. We had our last day in the cave yesterday, when we also spend some time on the surface together with Darron. We started by visiting the place where the river flows out after nearly 2kms underground. It’s a quite large river, […] Continue reading → 
Yesterday Darron and I found a hot spring in Gobholo Cave. Or rather a warm trickle of thermal water in a small passage that is a continuation of a passage formed in a remarkebly clear weakness zone/fissure zone. Is this a mere coincidence or are the fissures so deep that they can transport thermal water […] Continue reading → 
The distance Gobholo River flows underground, in a straight line and not taking the slope in account, is close to 1.7km. The 200 mapped meters of the cave does not include most of the known side passages. The innermost part is found 70m straight line from the entrance. With side passages that distance may hold […] Continue reading → 
202 meters and 43 meters, that’s the latest official length and depth, respectively, of Gobholo Caves, dating from Sunday. The last four days we have not mapped more in the cave; on monday we went together with Sipho upstreams the cave to where the river flows underground. Not much time in the afternoon when we […] Continue reading →

And taking pictures of course. I found quite a few entrances to the cave system, which […] Continue reading →

I’m expecting it to be way longer, it is a formidable labyrinth of passages everywhere — the number of survey loops […] Continue reading →
