watched us struggle to adjust, the anthropologist still floundering and apologizing for floundering. Later I realized I might have misread her expression; it might have been pained or self-pitying.
We were on a dirt trail strewn with pebbles, dead leaves, and pine needles damp to the touch. Velvet ants and tiny emerald beetles crawled over them. The tall pines, with their scaly ridges of bark, rose on both sides, and the shadows of flying birds conjured lines between them. The air was so fresh it buffeted the lungs and we strained to breathe for a few seconds, mostly from surprise. Then, after marking our location with a piece of red cloth tied to a tree, we began to walk forward, into the unknown. If the psychologist somehow became incapacitated and could not lead us across at the end of our mission, we had been told to return to await “extraction.” No one ever explained what form “extraction” might take, but the implication was that our superiors could observe the extraction point from afar, even though it was inside the border.
We had been told not to look back upon arrival, but I snuck a glance anyway, while the psychologist’s attention was elsewhere. I don’t know quite what I saw. It was hazy, indistinct, and already far behind us—perhaps a gate, perhaps a trick of the eye. Just a sudden impression of a fizzing block of light, fast fading.
The reasons I had volunteered were very separate from my qualifications for the expedition. I believe I qualified because I specialized in transitional environments, and this particular location transitioned several times, meaning that it was home to a complexity of ecosystems. In few other places could you still find habitat where, within the space of walking only six or seven miles, you went from forest to swamp to salt marsh to beach. In Area X, I had been told, I would find marine life that had adjusted to the brackish freshwater and which at low tide swam far up the natural canals formed by the reeds, sharing the same environment with otters and deer. If you walked along the beach, riddled through with the holes of fiddler crabs, you would sometimes look out to see one of the giant reptiles, for they, too, had adapted to their habitat.
I understood why no one lived in Area X now, that it was pristine because of that reason, but I kept un-remembering it. I had decided instead to make believe that it was simply a protected wildlife refuge, and we were hikers who happened to be scientists. This made sense on another level: We did not know what had happened here, what was still happening here, and any preformed theories would affect my analysis of the evidence as we encountered it. Besides, for my part it hardly mattered what lies I told myself because my existence back in the world had become at least as empty as Area X. With nothing left to anchor me, I needed to be here. As for the others, I don’t know what they told themselves, and I didn’t want to know, but I believe they all at least pretended to some level of curiosity. Curiosity could be a powerful distraction.
That night we talked about the tower, although the other three insisted on calling it a tunnel. The responsibility for the thrust of our investigations resided with each individual, the psychologist’s authority describing a wider circle around these decisions. Part of the current rationale for sending the expeditions lay in giving each member some autonomy to decide, which helped to increase “the possibility of significant variation.”
This vague protocol existed in the context of our separate skill sets. For example, although we had all received basic weapons and survival training, the surveyor had far more medical and firearms experience than the rest of us. The anthropologist had once been an architect; indeed, she had years ago survived a fire in a building she had designed, the only really personal thing I had found out about her. As for the psychologist, we knew the least about her, but I think we all believed she came from some kind of management background.
The discussion of the tower was, in a way, our first opportunity to test the limits of disagreement and of compromise.
“I don’t think we should focus on the tunnel,” the anthropologist said. “We should explore farther first, and we should come back to it with whatever data we gather from our other investigations—including of the lighthouse.”
How predictable, and yet perhaps prescient, for the anthropologist to try to substitute a safer, more comfortable option. Although the idea of mapping seemed perfunctory or repetitive to me, I could not deny the existence of the tower, of which there was no suggestion on any map.
Then the surveyor spoke. “In this case I feel that we should rule out the tunnel as something invasive or threatening. Before we explore farther. It’s like an enemy at our backs otherwise, if we press forward.” She had come to us from the military, and I could see already the value of that experience. I had thought a surveyor would always side with the idea of further exploration, so this opinion carried weight.
“I’m impatient to explore the habitats here,” I said. “But in a sense, given that it is not noted on any map, the ‘tunnel’ … or tower … seems important. It is either a deliberate exclusion from our maps and thus known … and that is a message of sorts … or it is something new that wasn’t here when the last expedition arrived.”
The surveyor gave me a look of thanks for the support, but my position had nothing to do with helping her. Something about the idea of a tower that headed straight down played with a twinned sensation of vertigo and a fascination with structure. I could not tell which part I craved and which I feared, and I kept seeing the inside of nautilus shells and other naturally occurring patterns balanced against a sudden leap off a cliff into the unknown.
The psychologist nodded, appeared to consider these opinions, and asked, “Does anyone yet have even an inkling of a sensation of wanting to leave?” It was a legitimate question, but jarring nonetheless.
All three of us shook our heads.
“What about you?” the surveyor asked the psychologist. “What is your opinion?”
The psychologist grinned, which seemed odd. But she must have known any one of us might have been tasked with observing her own reactions to stimuli. Perhaps the idea that a surveyor, an expert in the surface of things, might have been chosen, rather than a biologist or anthropologist, amused her. “I must admit to feeling a great deal of unease at the moment. But I am unsure whether it is because of the effect of the overall environment or the presence of the tunnel. Personally, I would like to rule out the tunnel.”
Tower.
“Three to one, then,” the anthropologist said, clearly relieved that the decision had been made for her.
The surveyor just shrugged.
Perhaps I’d been wrong about curiosity. The surveyor didn’t seem curious about anything.
“Bored?” I asked.
“Eager to get on with it,” she said, to the group, as if I’d asked the question for all of us.
We were in the communal tent for our talk. It had become dark by then and there came soon after the strange mournful call in the night that we knew must have natural causes but created a little shiver regardless. As if that was the signal to disband, we went back to our own quarters to be alone with our thoughts. I lay awake in my tent for a while trying to turn the tower into a tunnel, or even a shaft, but with no success. Instead, my mind kept returning to a question: What lies hidden at its base?
During our hike from the border to the base camp near the coast, we had experienced almost nothing out of the ordinary. The birds sang as they should; the deer took flight, their white tails exclamation points against the green and brown of the underbrush; the raccoons, bowlegged, swayed about their business, ignoring us. As a group, we felt almost giddy, I think, to be free after so many confining months of training and preparation. While we were in that corridor, in that transitional space, nothing could touch us. We were neither what we had been nor what we would become once we reached our destination.
The day before we arrived at the camp, this mood was briefly shattered by the appearance of an enormous wild boar some distance
