“I want you to know that I cannot stop thinking of it as a tower,” I confessed. “I can’t see it as a tunnel.” It seemed important to make the distinction before our descent, even if it influenced their evaluation of my mental state. I saw a tower, plunging into the ground. The thought that we stood at its summit made me a little dizzy.
All three stared at me then, as if I were the strange cry at dusk, and after a moment the psychologist said, grudgingly, “If that helps make you more comfortable, then I don’t see the harm.”
A silence came over us again, there under the canopy of trees. A beetle spiraled up toward the branches, trailing dust motes. I think we all realized that only now had we truly entered Area X.
“I’ll go first and see what’s down there,” the surveyor said, finally, and we were happy to defer to her.
The initial stairwell curved steeply downward and the steps were narrow, so the surveyor would have to back her way into the tower. We used sticks to clear the spiderwebs as she lowered herself into position on the stairwell. She teetered there, weapon slung across her back, looking up at us. She had tied her hair back and it made the lines of her face seem tight and drawn. Was this the moment when we were supposed to stop her? To come up with some other plan? If so, none of us had the nerve.
With a strange smirk, almost as if judging us, the surveyor descended until we could only see her face framed in the gloom below, and then not even that. She left an empty space that was shocking to me, as if the reverse had actually happened: as if a face had suddenly floated into view out of the darkness. I gasped, which drew a stare from the psychologist. The anthropologist was too busy staring down into the stairwell to notice any of it.
“Is everything okay?” the psychologist called out to the surveyor. Everything had been fine just a second before. Why would anything be different now?
The surveyor made a sharp grunt in answer, as if agreeing with me. For a few moments more, we could still hear the surveyor struggling on those short steps. Then came silence, and then another movement, at a different rhythm, which for a terrifying moment seemed like it might come from a second source.
But then the surveyor called up to us. “Clear to this level!” This level. Something within me thrilled to the fact that my vision of a tower was not yet disproven.
That was the signal for me to descend with the anthropologist, while the psychologist stood watch. “Time to go,” the psychologist said, as perfunctorily as if we were in school and a class was letting out.
An emotion that I could not quite identify surged through me, and for a moment I saw dark spots in my field of vision. I followed the anthropologist so eagerly down through the remains of webs and the embalmed husks of insects into the cool brackishness of that place that I almost tripped her. My last view of the world above: the psychologist peering down at me with a slight frown, and behind her the trees, the blue of the sky almost blinding against the darkness of the sides of the stairwell.
Below, shadows spread across the walls. The temperature dropped and sound became muffled, the soft steps absorbing our tread. Approximately twenty feet beneath the surface, the structure opened out into a lower level. The ceiling was about eight feet high, which meant a good twelve feet of stone lay above us. The flashlight of the surveyor’s assault rifle illuminated the space, but she was faced away from us, surveying the walls, which were an off-white and devoid of any adornment. A few cracks indicated either the passage of time or some sudden stressor. The level appeared to be the same circumference as the exposed top, which again supported the idea of a single solid structure buried in the earth.
“It goes farther,” the surveyor said, and pointed with her rifle to the far corner, directly opposite the opening where we had come out onto that level. A rounded archway stood there, and a darkness that suggested downward steps. A tower, which made this level not so much a floor as a landing or part of the turret. She started to walk toward the archway while I was still engrossed in examining the walls with my flashlight. Their very blankness mesmerized me. I tried to imagine the builder of this place but could not.
I thought again of the silhouette of the lighthouse, as I had seen it during the late afternoon of our first day at base camp. We assumed that the structure in question was a lighthouse because the map showed a lighthouse at that location and because everyone immediately recognized what a lighthouse should look like. In fact, the surveyor and anthropologist had both expressed a kind of relief when they had seen the lighthouse. Its appearance on both the map and in reality reassured them, anchored them. Being familiar with its function further reassured them.
