We took the mules and headed up the hill. It was pretty rough going; the mules seemed okay, but I found some of the steeper climbs problematic. There doesn't seem to be any plant life on the hill at all, and when we lost sight of the camp, we might as well have been on the moon.
We've made it about halfway up. Progress is slow because we can only follow certain routes, and if they come to a dead end, we have to double back and try a different path. I'm exhausted, and I don't know if I'll sleep. It's one thing to sleep out in The Sick Land with everyone else at the camp, but quite another to be up here on the hill. It's very easy to feel like you're alone in an alien world.
