At first, only I saw it as a tower. I don’t know why the word tower came to me, given that it tunneled into the ground. I could as easily have considered it a bunker or a submerged building. Yet as soon as I saw the staircase, I remembered the lighthouse on the coast and had a sudden vision of the last expedition drifting off, one by one, and sometime thereafter the ground shifting in a uniform and preplanned way to leave the lighthouse standing where it had always been but depositing this underground part of it inland. I saw this in vast and intricate detail as we all stood there, and, looking back, I mark it as the first irrational thought I had once we had reached our destination.
“This is impossible,” said the surveyor, staring at her maps. The solid shade of late afternoon cast her in cool darkness and lent the words more urgency than they would have had otherwise. The sun was telling us that soon we’d have to use our flashlights to interrogate the impossible, although I’d have been perfectly happy doing it in the dark.
“And yet there it is,” I said. “Unless we are having a mass hallucination.”
“The architectural model is hard to identify,” the anthropologist said. “The materials are ambiguous, indicating local origin but not necessarily local construction. Without going inside, we will not know if it is primitive or modern, or something in between. I’m not sure I would want to guess at how old it is, either.”
We had no way to inform our superiors about this discovery. One rule for an expedition into Area X was that we were to attempt no outside contact, for fear of some irrevocable contamination. We also took little with us that matched our current level of technology. We had no cell or satellite phones, no computers, no camcorders, no complex measuring instruments except for those strange black boxes hanging from our belts. Our cameras required a makeshift darkroom. The absence of cell phones in particular made the real world seem very far away to the others, but I had always preferred to live without them. For weapons, we had knives, a locked container of antique handguns, and one assault rifle, this last a reluctant concession to current security standards.
It was expected simply that we would keep a record, like this one, in a journal, like this one: lightweight but nearly indestructible, with waterproof paper, a flexible black-and-white cover, and the blue horizontal lines for writing and the red line to the left to mark the margin. These journals would either return with us or be recovered by the next expedition. We had been cautioned to provide maximum context, so that anyone ignorant of Area X could understand our accounts. We had also been ordered not to share our journal entries with one another. Too much shared information could skew our observations, our superiors believed. But I knew from experience how hopeless this pursuit, this attempt to weed out bias, was. Nothing that lived and breathed was truly objective—even in a vacuum, even if all that possessed the brain was a self-immolating desire for the truth.
“I’m excited by this discovery,” the psychologist interjected before we had discussed the tower much further. “Are you excited, too?” She had not asked us that particular question before. During training, she had tended to ask questions more like “How calm do you think you might be in an emergency?” Back then, I had felt as if she were a bad actor, playing a role. Now it seemed even more apparent, as if being our leader somehow made her nervous.
“It is definitely exciting … and unexpected,” I said, trying not to mock her and failing, a little. I was surprised to feel a sense of growing unease, mostly because in my imagination, my dreams, this discovery would have been among the more banal. In my head, before we had crossed the border, I had seen so many things: vast cities, peculiar animals, and, once, during a period of illness, an enormous monster that rose from the waves to bear down on our camp.
The surveyor, meanwhile, just shrugged and would not answer the psychologist’s question. The anthropologist nodded as if she agreed with me. The entrance to the tower leading down exerted a kind of presence, a blank surface that let us write so many things upon it. This presence manifested like a low-grade fever, pressing down on all of us.
I would tell you the names of the other three, if it mattered, but only the surveyor would last more than the next day or two. Besides, we were always strongly discouraged from using names: We were meant to be focused on our purpose, and “anything personal should be left behind.” Names belonged to where we had come from, not to who we were while embedded in Area X.

Originally our expedition had numbered five and included a linguist. To reach the border, we each had to enter a separate bright white room with a door at the far end and a single metal chair in the corner. The chair had holes along the sides for straps; the implications of this raised a prickle of alarm, but by then I was set in my determination to reach Area X. The facility that housed these rooms was under the control of the Southern Reach, the clandestine government agency that dealt with all matters connected to Area X.
