screen through many a long evening, mystified.
Every day she drove, then walked. She left the ice sea, and continued north onto Acidalia.
The great plains of the northern hemisphere were generally referred to as level, and they certainly were compared to the chaoses, or to the southern highlands. But still, they were not level like a playing field, or a table top—not even close. There were undulations everywhere, a continuous up-and-downing of hummocks and hollows, ridges of cracking bedrock, hollows of fine drifts, great rumpled boulder fields, isolated tors and little sinkholes … It was unearthly. On Earth, soil would have filled the hollows, and wind and water and plant life would have worn down the bare hilltops, and then the whole thing would have been submerged or subducted or worn flat by ice sheets, or uplifted by tectonic action, everything torn away and rebuilt scores of times as the eons passed, and always flattened by weather and biota. But these ancient corrugated plains, their hollows banged out by meteor impact, had not changed for a billion years. And they were among the youngest surfaces on Mars.
It was a hard thing to drive across such lumpy terrain, and very easy to get lost when out walking, particularly if one’s car looked just like all the other boulders scattered about; particularly if one were distracted. More than once Ann had to find the car by radio signal rather than visual sighting, and sometimes she walked right up to it before recognising it—and then would wake up, or come to, hands shaking in the aftershock of some forgotten reverie.
The best driving routes were along the low ridges and dikes of exposed bedrock. If these high basalt roads had connected one to the next, it would have been easy. But they commonly were broken by transverse faults, at first no more than line cracks, which then got deeper and wider as one progressed, in sequences like loaves of sliced bread tipping open, until the faults gaped and were filled with rubble and fines, and the dike became nothing but part of a boulder field again.
She continued north, onto Vastitas Borealis. Acidalia, Borealis: the old names were so strange. She was doing her best never to think, but during the long hours in the car it was sometimes impossible. At those times it was less dangerous to read than it was to try staying blank. So she would read randomly in her AI’s library. Often she ended up staring at areological maps, and one evening at sunset after such a session, she looked into this matter of Mars’s names.
It turned out most of them came from Giovanni Schiaparelli. On his telescope maps he had named over a hundred albedo features, most of which were just as illusory as his canali. But when the astronomers of the 1950s had regularised a map of the albedo features everyone could agree on—features that could be photographed—many of Schiaparelli’s names had been retained. It was a tribute to a certain power he had had, a power evocative if not consistent; he had been a classical scholar, and a student of Biblical astronomy, and among his names there were Latin, Greek, Biblical, and Homeric references, all mixed together. But he had had a good ear, somehow. One proof of his talent was the contrast between his maps and competing Martian maps of the nineteenth century. A map by an Englishman named Proctor, for instance, had relied on the sketches of a Reverend William Dawes; and so on Proctor’s Mars, which had no recognisable relations even to the standard albedo features, there was a Dawes Continent, a Dawes Ocean, a Dawes Strait, a Dawes Sea, and a Dawes Forked Bay. Also an Airy Sea, a DeLaRue Ocean, and a Beer Sea. Admittedly this last was a tribute to a German named Beer, who had drawn a Mars map even worse than Proctor’s. Still, compared to them Schiaparelli had been a genius.
But not consistent. And there was something wrong in this mélange of references, something dangerous. Mercury’s features were all named after great artists, Venus’s were named after famous women; they would drive or fly over those landscapes one day, and feel that they lived in coherent worlds. Only on Mars did they walk about in a horrendous mishmash of the dreams of the past, causing who knew what disastrous misapprehensions of the real terrain: the Lake of the Sun, the Plain of Gold, the Red Sea, Peacock Mountain, the Lake of the Phoenix, Cimmeria, Arcadia, the Gulf of Pearls, the Gordian Knot, Styx, Hades, Utopia …
On the dark dunes of Vastitas Borealis she began to run low on supplies. Her seismographs showed daily tremblors to the east, and she drove toward them. On her walks outside she studied the garnet sand dunes, and their layering which revealed the old climates like tree rings. But snow and high winds were tearing off the crests of the dunes. The westerlies could be extremely strong, enough to pick up sheets of large-grained sand and hurl them against her car. The sand would always settle in dune formations, as a simple matter of physics, but the dunes would be picking up the pace of their slow march around the world, and the record they had made of earlier ages would be destroyed.
She forced that thought from her mind, and studied the phenomenon as if there were no new artificial forces disturbing it. She focused on her work as if clenching her geologist’s hammer, as if breaking apart rocks. The past was spalled away piece by piece. Leave it behind. She refused to think of it. But more than once she jerked out of sleep with the image of the long runout coming at her. And then she was awake for good, sweating and trembling, faced with the incandescent dawn, the sun blazing like a chunk of burning sulphur.
Coyote had given her a map of his caches in the north, and now she came to one buried in a cluster of house-sized boulders. She restocked, leaving a brief thank-you note. The last itinerary Coyote had given her said he was going to be dropping by this area sometime soon, but there was no sign of him, and no use waiting. She drove on.
She drove, she walked. But she couldn’t help it; the memory of the landslide haunted her. What bothered her was not that she had had a brush with death, which no doubt had happened many times before, mostly in ways she had not noticed. It was simply how arbitrary it had been. It had nothing to do with value or fitness; it was pure contingency. Punctuated equilibrium, without the equilibrium. Effects did not follow from causes, and one did not get one’s just deserts. She was the one who had spent too much time outdoors, after all, taking on far too much radiation; but it was Simon who had died. And she was the one who had fallen asleep at the wheel; but it was Frank who had died. It was simply a matter of chance, of accidental survival or erasure.
It was hard to believe natural selection had made any way in such a universe. There under her feet, in the troughs between the dunes, Archae bacteria were growing on sand grains; but the atmosphere was gaining oxygen fast, and all the Archae bacteria would die out except those that were by accident underground, away from the oxygen they themselves had respired, the oxygen that was poisonous to them. Natural selection or accident? You stood, breathing gases, while death rushed toward you—and were covered by boulders, and died—or covered by dust, and lived. And nothing you did mattered in that great either/or. Nothing you did mattered. One afternoon, reading randomly in the AI to distract herself between her return to the car and her dinner hour, she learned that the Czarist police had taken Dostoevsky out to be executed, and only brought him back in after several hours of waiting for his turn. Ann finished reading about this incident and sat in the driver’s seat of her car, feet on the dash, staring at the screen blindly. Another garish sunset poured through the window over her, the sun weirdly large and bright in the thickening atmosphere. Dostoevsky had been changed for life, the writer declared in the easy omniscience of biography. An epileptic, prone to violence, prone to despair. He hadn’t been able to integrate the experience. Perpetually angry. Fearful. Possessed.
Ann shook her head and laughed, angry at the idiot writer, who simply didn’t understand. Of course you didn’t integrate the experience. It was meaninglessness. The experience that couldn’t be integrated.
The next day a tower poked over the horizon. She stopped the car, stared at it through the car’s telescope. There was a lot of ground mist behind it. The tremblors registering on her seismograph were very strong now, and appeared to be coming from a bit to the north. She even felt one of them herself, which, given the car’s shock absorbers, meant they were strong indeed. It seemed likely there was a connection with the tower.
