The strong rainfall in the Peak was quite interesting for me to see response times for water, very heavy rain throughout the morning, we were underground at around 10:30 so not sure how much fell after that.
Barely a trickle in Titan then, and no water at all coming from the Stemple Highway junction. On the way back at around 16:00 there was a strong flow coming from the junction, and probably the 2nd worst dousing I've gotten on Titan so far. Even then it's nowhere near truly impassable, just unpleasant as the entire bottom pitch is a case of "hood up, head down, keep going". Wellies filled with water running down the inside of my oversuit.
The flow of water down the Event Horizon ledge had started to flush some rocks down close to the lip, so picked those up and stashed them in "safer" places.
