I haven't read the entire log, but there should be competing adventurers. Maybe from the same society, maybe from a competingb society. Then people could say "Oh, damn it, it's Sir Mustache's expedition again! It's like they somehow always know where we're going. Well, this time we're not letting them beat us to the punch!" It could help keep people from dawdling (unless the players decide to try to burn their camp while they sleep).
Maybe even from different countries, like ze German adwenturers or Thpanith conquistadors with funny haths. It would help add some opportunities for competition or diplomacy (and would inevitably lead to sabotage, war or war by proxy).
EDIT: Oh, and I had a dream that in a twist ending ended up being ER related. The perspective I was following was a man going through a futuristic city that was suffering from a zombie Apocalypse along with his team. I don't remember the details, but the team somehow ended up dead or infected and the man who's eyes I was watching through (I could tell it wasn't me because I couldn't hear his thoughts) was the only one left. He finally reached a military facility, where a soldier urged him into an elevator and to the medical level. I saw the soldier get attacked and die through the elevator's glass door as it got higher and higher until the elevator exited the lobby and entered a concrete shaft.
In there, a zombie capybara suddenly burst through the elevator floor and tried to attack the protagonist. He managed to kick it and punch it until it fell down the elevator shaft, but got a small cut in the process.
The moment he arrived to the medical level, he was greeted by a man in fullbody white suits, doctor's mask and safety goggles. As he explained to him that he was scratched and that he needs help, he was taken through rooms with more of those men in white and had some liquids and a strange plastic device applied to his scratch.
He reached a quarantine area where the head doctor pointed him to a transparent cell from his desk which was right opposite to the cells. But the cell was full of blood and there was a mutilated zombie strapped to a bed there. The protagonist said he can't stay in such a crappy room full of blood and asked what he should do about it and the head doctor told him to take a mop and clean it up. The protagonist shrugged and asked if it was dead and the doctor replied "Sure." and pressed a button to demonstrate. There was a sound of capacitors charging and the mutilated zombie spasmed but remained down and unmoving, but the other zombies in the other cells also got hit by electricity and got agitated. They started banging on their doors, causing cracks to appear. The protagonist grabbed a fire extinguisher, opened a door and started bashing one of the agitated zombie's head in. The doctor liked the initiative he displayed and ordered some security guards to follow his example. The guards grabbed heavy objects and started doing the same, until one of them was bit. He started panicking, got into an argument with the others, said something about being "better with the zombies than with you!" and opened all the doors, releasing all the zombies. The protagonist tried to fight, but more and more were coming from other rooms. Everyone died, everyone but him and the doctor, the doctor who was watching him from his desk while the zombies completely ignored him, even though they passed right next to his desk.
Until the main character realized there were far too many zombies. In fact, there were impossibly many zombies. They were coming from everywhere, even appearing in cells that should be empty. That's when he realized that this isn't real and said "This is not real. But we're all going to die here." At that point, the zombies slowed down and the phone of the main desk started ringing. The head doctor, who continued to be incredibly calm and ignored by zombies slowly picked up the phone and said "Indeed. You're all going to die here." as he put it in his ear. After a small delay he extended his hand and offered the man the phone, saying "It's for you."
The man runs to the desk and picks up the phone, frantically trying to avoid the zombies who are slowly getting closer. The voice in the phone identified itself as Steve and told the man, who he called Miyamoto, that he did good and that he can exit now. An elevator door behind the doctor opened. The man jumped over the desk and entered the elevator, the doors closing behind him. As the elevator descended, the voice calling itself Steve told the protagonist that humanity needed him and that he needed the protagonist to become a leader. He also needed him to create a team of powerful individuals who were not constrained by morals for a mission of great importance. He said the future of humanity depended on it. (Kinda reminded me of god saving a man and then telling him to become a prophet) The elevator doors opened into a thin deep red sandy canyon with small caves on its walls and strangely angular shape. He noticed that the gravity was lower (I guessed it was Mars). The protagonist kept walking around until he caught sight of a smiling young man. He wore grey-white clothes without shoes and he somehow looked luminous, like he was reflecting sunlight despite standing in the shade. He turned around and walked away. When the protagonist tried to follow him, the only thing he found was a single footstep in the sand. That's when he realised that he was not leaving any footsteps either. He kept going the way the smiling young man went until he reached a dark cave.
There was water falling from the ceiling of the cavern, forming a puddle in a strange crater. There was also a cable running along the ceiling, going to a tall black triangular machine that looked inactive. The protagonist looked at the crater until he realised it wasn't a crater but human footprints. Several of them in the exact same spot, each of them larger than the previous one, so large they caused a hole to appear in the wall. Like a four dimensional footstep was compressed in three dimensional space.
The protagonist looked up and saw a hole in the ceiling. He flapped his arms and started flying. He went through the hole. The sun had just set. But he could still see the city. Or at least its outline. A human city, incredibly advanced and yet abandoned, only a few of its lights still on, probably automated. After flying for a while, he turned his eyes towards the sky and started flying towards it. Night was coming and the stars were appearing. One star kept getting larger and brighter, so bright it caused others to disappear.
The protagonist woke up in a dark room and after a few seconds of contemplation and quick breathing, he said "I know what to do."
