Tithonium was one of the deepest and narrowest of the Marineris canyons— four kilometers deep, ten wide. He could fly well below the level of the plateau rims and still be thousands of meters over the canyon floor. Tithonium was higher than Ius, wilder, untouched by human hands, seldom traveled in, because it was a dead end to the east, where it narrowed and became rough-floored as it got shallower, then abruptly stopped. Nirgal spotted the road that switchbacked up the eastern head wall, a road he had traveled a few times in his youth, when all the planet had been his home.
The afternoon sun dipped behind him. The shadows on the land lengthened. The wind continued to blow strong, thrumming over the blimpglider, whining and whooshing and keening. It blew him over the caprock of the rim plateau again, as Tithonium became a string of oval depressions, pocking the plateau one after the next: the Tithonia Catena, each dip a giant bowl-shaped depression in the land.
And then suddenly the world dropped away again, and he flew out over the immense open canyon of Candor Chasma, Shining Canyon, the ramparts of its eastern wall in fact shining at that very moment, amber and bronze in the sunset’s light. To the north was the deep entrance to Ophir Chasma, to the south the spectacular buttress-walled opening down to Melas Chasma, the central giant of the Marineris system. It was Mars’s version of Concordiaplatz, he saw, but much bigger than Earth’s, wilder, looking untouched, primal, gigantic beyond all human scale, as if he had flown back two centuries into the past, or two eons, to a time before the anthropogenesis. Red Mars!
And there out in the middle of broad Candor was a tall diamond mesa, a caprock island standing nearly two kilometers above the canyon floor. And in the sunset’s hazy gloom Nirgal could make out a nest of lights, a tent town, at the southernmost point of the diamond. Voices welcomed him over the common band on his intercom, then guided him in to the town’s landing pad. The sun was winking out over the cliffs to the west as he brought the blimpglider around and descended slowly into the wind, putting it down right on the figure of Kokopelli painted as a target on the landing pad.
Shining Mesa had a large top, more a kite shape than a diamond proper, thirty kilometers long and ten wide, standing in the middle of Candor Chasma like a Monument Valley mesa writ large. The tent town occupied only a small rise on the southern point of the kite. The mesa was just what it appeared to be, a detached fragment of the plateau that the Marineris canyons had split. It was a tremendous vantage point for viewing the great walls of Candor, with views through the deep, steep gaps into Ophir Chasma to the north and Melas Chasma to the south.
Naturally such a spectacular prospect had attracted people over the years, and the main tent was surrounded by new smaller ones. At five kilometers above the datum, the town was still tented, though there was talk of removing it. The floor of Candor Chasma, only three kilometers above the datum, was patched with growing dark green forests. Many of the people who lived on Shining Mesa flew down into the canyons every morning to farm or botanize, floating back up to the mesa’s top in the late afternoons. A few of these flying foresters were old underground acquaintances of Nirgal’s, and they were pleased to take him along and show him the canyons, and what they did in them.
The Marineris canyon floors generally run down west to east. In Candor, they curved around the great central mesa, then fell precipitously south into Melas. Snow lay on the higher parts of the floor, especially under the western walls where shadows lay in the afternoon. Meltwater from this snow ran down in a faint tracery of new watersheds, made up of sandy braided streambeds that ran together into a few shallow muddy red rivers, which collected at a confluence just above the Candor Gap, and poured down in a wild foaming rapids to the floor of Melas Chasma, where it pooled against the remnant of the 61 glacier, running redly against its northern flank.
On the banks of all these opaque red streams, forest galleries were springing up. They consisted in most places of cold-hardened balsas and other very rapidly growing tropical trees, creating new canopies over older krummholz. These days it was warm on the canyon floor, which was like a big sun-reflecting bowl, protected from the wind. The balsa canopies were allowing a great number of plant and animal species to flourish underneath them; Nirgal’s acquaintances said it was the most diverse biotic community on Mars. They had to carry sedative dart guns now when they landed and walked around, because of bears, snow leopards, and other predators. Walking through some of the galleries was becoming difficult because of thickets of snow bamboo and aspen.
All this growth had been aided by huge deposits of sodium nitrate that had been lying in Candor and Ophir canyons— great white bench terraces made of extremely water-soluble caliche blanco. These mineral deposits were now melting over the canyon floors and running down the streams, providing the new soils with lots of nitrogen. Unfortunately some of the biggest nitrate deposits were being buried under landslides— the water that was dissolving the sodium nitrate was also hydrating the canyon walls, destabilizing them in a radical acceleration of the mass wasting that went on all the time. No one went near the foot of the canyon walls anymore, the fliers said: too dangerous. And as they soared around in their blimpgliders, Nirgal saw the scars of landslides everywhere. Several high talus plant slopes had been buried, and wall-fixing methods were one of the many topics of conversation in the mesa evenings, after the omegandorph got into the blood; in fact there was little they could do. If chunks of a ten-thousand-foot-high wall of rock wanted to give way, nothing was going to stop them. So from time to time, about once a week or so, everyone on Shining Mesa would feel the ground quiver, watch the tent shimmer, and hear in the pit of the stomach the low rumble of a collapse. Often it was possible to spot the slide, rolling across the canyon floor ahead of a sienna billow of dust. Fliers in the air nearby would come back shaken and silent, or voluble with tales of being slapped across the sky by earsplitting roars. One day Nirgal was about halfway down to the floor when he felt one himself: it was like a sonic boom that went on for many seconds, the air quivering like a gel. Then, just as suddenly as it had begun, it was over.
Mostly he explored on his own, sometimes he flew with his old acquaintances. Blimpgliders were perfect for the canyon, slow and steady, easy to steer. More loft than was needed, more power . . . the one he had rented (using money from Coyote) allowed him to drift down in the mornings to help botanize in the forests, or walk by the streams; then float back up through the afternoons, up and up and up and up. This was when one got a true sense of just how tall Candor Mesa was, and the even taller canyon walls— up up and up and up, to the tent and its long meals, its party nights. Day after day Nirgal followed this routine, exploring the various regions of the canyons below, watching the exuberant nightlife in the tent; but seeing everything as if through the wrong end of a telescope, a telescope consisting of the question Is this the life I want to lead? This distancing and somehow miniaturizing question kept returning to him, spurring him by day as he banked in the sunlight, haunting him at night in sleepless hours between the timeslip and dawn. What was he to do? The success of the revolution had left him without a task. All his life he had wandered Mars talking to people about a free Mars, about inhabitation rather than colonization, about becoming indigenous to the land. Now that task was ended, the land was theirs to live on as they chose. But in this new situation he found he did not know his part. He had to think very specifically about how to go on in this new world, no longer as the voice of the collective, but as an individual in his own private life.
He had discovered that he did not want to continue working on the collective; it was good that some people wanted to do it, but he wasn’t one of them. In fact he could not think about Cairo without a stab of anger at Jackie, and of simple pain as well— pain at the loss of that public world, that whole way of life. It was hard to give up being a revolutionary. Nothing seemed to follow from it, either logically or emotionally. But something had to be done. That life was past. In the midst of a banking slow dive in his blimpglider, he su
ddenly understood Maya and her obsessive talk about incarnations. He was twenty-seven m-years old now, he had crisscrossed all Mars, he had been to Earth, he had returned to a free world. Time for the next metempsychosis.
So he flew around the immensities of Candor, looking for some image of himself. The fractured, layered, scarred canyon walls were so many stupendous mineral mirrors; and indeed he saw clearly that he was a tiny creature, smaller than a gnat in a cathedral. Flying around studying each great palimpsest of facets, he scried two very strong impulses in himself, distinct and mutually exclusive, yet infolded, like the green and the white. On the one hand he wanted to stay a wanderer, to fly and walk and sail over all the world, a nomad forever, wandering ceaselessly until he knew Mars better than anyone else. Ah yes; it was a familiar euphoria. On the other hand it was familiar, he had done that all his life. It would be the form of his previous life, without the content. And he knew already the loneliness of that life, the rootlessness that made him feel so detached, that gave him this wrong-end-of-the-telescope vision. Coming from everywhere he came from nowhere. He had no home. And so now he wanted that home, as much as the freedom or more. A home. He wanted to settle into a full human life, to pick a place and stay there, to learn it completely, in all its seasons, to grow his food, make his house and his tools, become part of a community of friends.
Both these desires existed, strongly and together— or, to be more exact, in a subtle rapid oscillation, which jangled his emotions, and left him insomniac and restless. He could see no way to reconcile the two. They were mutually exclusive. No one he talked to had any useful suggestions as to how to resolve the difficulty. Coyote was dubious about setting down roots— but then he was a nomad, and didn’t know. Art considered the wandering life impossible; but he was fond of his places now.
Nirgal’s nonpolitical training was in mesocosm engineering, but he found that little help to his thinking. At the higher elevations they were always going to be in tents, and mesocosm engineering would be needed; but it was becoming more of a science than an art, and with increasing experience solving the problems would be more and more routinized. Besides, did he want to pursue a tented profession, when so much of the lower planet was becoming land they could walk on?
No. He wanted to live in the open air. To learn a patch of land, its soil and plants and animals and weather and skies, and everything else . . . he wanted that. Part of him. Part of the time.
He began to feel, however, that whatever he chose, Candor Chasma was not the place for the kind of settlement he was thinking of. Its huge vistas made it a hard place to see as home— it was too vast, too inhuman. The canyon floors were designed and designated as wilderness, and every spring the streams surging with snowmelt would jump their banks, tear new channels, be buried under enormous landslides. Fascinating, all of it. But not home. The locals were going to stay up on Shining Mesa, and only visit the canyon floors during the day. The mesa would be their true home. It was a good plan. But the mesa— it was an island in the sky, a great tourist destination, a place for flying vacations, for partying through the nights, for expensive hotels, for the young and the in-love . . . all that was fine, wonderful. But crowded, perhaps even overrun— or else always battling the influx of visitors, and newly settled residents enchanted by the sublime views, people who would arrive like Nirgal himself, dropping in at some dusk in their life and never going away, while the old residents looked on helplessly and grumbled about the good old days when the world had been new, and unoccupied.
No— that was not the kind of home he had in mind. Although he loved the way dawn flushed the fluted west walls of Candor, flaring all across the Martian spectrum, the sky turning indigo or mauve, or a startling earthly cerulean . . . a beautiful place, so beautiful that on some days as he flew about he felt it would be worth it to stand on Shining Mesa and hold his ground, to try to preserve it, to swoop down and learn the gnarly wilderness floor, float back up every afternoon to dinner. Would that work, make him feel at home? And if wilderness was what he wanted, weren’t there other places less spectacular but more remote, thus more wild?
Back and forth he went, back and forth. One day, flying over the foaming opaque series of waterfalls and rapids in the Candor Gap, he remembered that John Boone had been through this area, in a solo rover just after the Transmarineris Highway had been built. What would that master equivocator have said about this amazing region?
Nirgal called up Boone’s AI, Pauline, and asked for Candor, and found a voice diary made during a drive through the canyon in 2046. Nirgal let the tape run as he looked down on the land from above, listening to the hoarse voice with the friendly American accent, a voice unselfconscious about talking to an AI. Listening to the voice made Nirgal wish he could really talk to the man. Some people said Nirgal had filled John Boone’s empty shoes, that Nirgal had done the work John would have done had he lived. If that were so, what would John have done afterward? How would he have lived?
“This is the most unbelievable country I’ve ever seen. Really, it’s what you think of when you think of Valles Marineris. Back in Melas the canyon was so wide that out in the middle you couldn’t see the walls at all, they were under the horizon! This small-planet curvature is producing effects no one ever imagined. All the old simulations lied so bad, the verticals exaggerated by factors of five or ten, as I recall, which made it look like you were down in a slot. It’s not a slot. Wow, there’s a rock column just like a woman in a toga, Lot’s wife I guess that would be. I wonder if it is salt, it’s white, but I guess that doesn’t mean much. Have to ask Ann. I wonder what those Swiss road builders made of all this when they built this road, it’s not very alpine. Kind of like an anti-Alps, down instead of up, red instead of green, basalt instead of granite. Well, but they seemed to like it anyway. Of course they’re anti-Swiss Swiss, so it makes a kind of sense. Whoa, pothole country here, the rover is bouncing around. Might try that bench there, it looks smoother than here. Yep, there we go, just like a road. Oh— it is the road. I guess I got off it a bit, I’m driving manually for the fun of it, but it’s hard to keep an eye out for the transponders when there’s so much else to look at. The transponders are made more for automatic pilot than the human eye. Hey, there’s the break into Ophir Chasma, what a gap! That wall must be, I don’t know— twenty thousand feet tall. My Lord. Since the last one was called Candor Gap, this one should be called Ophir Gap, right? Ophir Gate would be nicer. Let’s check the map. Hmm, the promontory on the west side of the gap is called Candor Labes, that’s lips, isn’t it? Candor Throat. Or, hmm. I don’t think so. It’s one hell of an opening though. Steep cliffs on both sides, and twenty thousand feet tall. That’s about six or seven times as tall as the cliffs in Yosemite. Sheeee-it. They don’t look that much taller, to tell the truth. Foreshortening no doubt. They look about twice as tall, or— who knows. I can’t remember what Yosemite really looked like, in terms of size anyway. This is the most amazing canyon you could ever even imagine. Ah, there’s Candor Mensa, on my left. This is the first time I could see that it isn’t part of the Candor Labes wall. I’ll bet that mesa top has one hell of a view. Put a fly-in hotel up there, sure. I wish I could get up there and see it! This would be a fun place to fly around in. Dangerous though. I see dust devils every now and then, vicious little things, real tight and dark. There’s a shaft of sunlight there hitting the mesa through the dust. Like a bar of butter hanging in the air. Ah, God, what a beautiful world!”
Nirgal could only agree. It made him laugh to hear the man’s voice, and surprised him to hear John talk about flying above. It made him understand a little bit the way the issei talked about Boone, the hurt in them that never went away. How much better it would be to have John here than just these recordings in an AI, what a great adventure it would have been to watch John Boone negotiate Mars’s wild history! Saving Nirgal the burden of that role, among other things. As it was, however, they only had that friendly happy voice. And that did not solve his problem.

Back up on Candor Mesa, the fliers met at night in a ring of pubs and restaurants placed on the high southern arc of their tent wall, where on terraces just inside the tent they could sit and look out at the long views, over the forested world of their domain. Nirgal sat among these people, eating and drinking, listening, sometimes talking, thinking his own thoughts among them, comfortably; they did not care what had happened to him on Earth, they did not care that he was there among them. This was good, as often he was distracted to the point of being oblivious to his surroundings; he would fall into reveries and come out of them, and realize that once again he had been in the steamy streets of Port of Spain, or in the refugee compound in the torrential monsoon. How often he found himself there again; everything that had happened since was so pale by comparison!
But one night he came to from a reverie, having heard some voice say “Hiroko.”
“What’s that?” he said.
“Hiroko. We met her flying around Elysium, up on its north slope.”
It was a young woman speaking, her face innocent of any knowledge of who he was.
“You saw her yourself?” he said sharply.
“Yes. She’s not hiding or anything. She said she liked my flier.”
“I don’t know,” an older man said. A Mars vet, an issei immigrant from the early years, his face battered by wind and cosmic rays until it looked like leather. Voice hoarse: “I heard she was down in the chaos where the first hidden colony used to be, working on the new harbors in the south bay.”
Other voices cut in: Hiroko had been seen here, had been seen there, had been confirmed dead, had gone to Earth; Nirgal had seen her there on Earth—
