We made it to the top of the hill today, to a point where we could see over to the other side. There's no crater. Just more of the same terrain. I can't say I'm surprised: I was expecting this. The rest of the team didn't seem too disappointed, either. They must have suspected that we hadn't stumbled over something people have been searching for for the last hundred years. Anyway, we still get to explore the cavern, assuming the rest of them haven't already done everything by the time we get back.
We're some of the way down the hill already, and we know the route now. We should be at the base camp by tomorrow afternoon. It'll be good to get back.
