Got through all the bits the other lot rigged and then to the biggest pitch. A horrid traverse over a ~25m pitch, which was really horrid on the way back up. At the bottom of the pitch was a longish traverse that was awkward but not dangerous. The way we went ended. On the way we saw a few places to squeeze down to the streamway. The couple of draughting passages we found were too tight.
The first few pitches (descended the day before) are lots longer than they reckoned.
