So, let's go then.

The track we drove down had recently been cleared. There were also a lot of other tracks in a similar condition, branching off in various directions. Most of these just led to random fields though, and had presumably been cleared for the benefit of local farmers. We stuck to the main track until we came to this side road. It led down to what looked like a dried-up river bed, and we wanted to check it out.

Yes, that is exactly what it was. I would love to see this during the rainy season, but I would imagine the road down would be quite treacherous when wet.

I gave a warning about snakes earlier on in the blog. At a location like this you need to be extra careful.

When you are exploring, you should always park somewhere sensible. In this case, I parked at the top of this slope. Had I driven all the way down to the river bed, I would have had to reverse back up it. Far easier just to walk.
