Sabishii was located on the western side of a five-kilometer-high prominence called the Tyrrhena massif; south of Jarry-Desloges Crater, in the ancient highlands between Isidis and Hellas, centered at longitude 275 degrees, latitude 15 degrees south. A reasonable choice for a tent-town site, as it had long views to the west, and low hills backing it to the east, like moors. But when it came to living in the open air, or growing plants out in the rocky countryside, it was a bit high; in fact it was, if you excluded the very much larger bulges of Tharsis and Elysium, the highest region on Mars, a kind of bioregion island, which the Sabishiians had been cultivating for decades.
They proved to be severely disappointed by the loss of the big mirrors, one might even say thrown into emergency mode, an all-out effort to do what they could to protect the plants of the biome; but it was precious little. Sax’s old colleague Nanao Nakayama shook his head. “Winterkill will be very bad. Like ice age.”
“I’m hoping we can compensate for the loss of light,” Sax said. “Thicken the atmosphere, add greenhouse gases— it’s possible we could do some of that with more bacteria and suralpine plants, right?”
“Some,” Nanao said dubiously. “A lot of niches are already full. The niches are quite small.”
They settled in over a meal to talk about it. All the techs from Da Vinci were there in the big dining hall of The Claw, and many Sabishiians were there to greet them. It was a long, interesting, friendly talk. The Sabishiians were living in the mound maze of their mohole, behind one talon of the dragon figure it made, so that they didn’t have to look at the burned ruins of their city when they weren’t working on it. The rebuilding was much reduced now, as most of them were out dealing with the results of the mirror loss. Nanao said to Tariki, in what was clearly the continuation of a long-standing argument, “It makes no sense to rebuild it as a tent city anyway. We might as well wait, and build it in open air.”
“That may be a long wait,” Tariki said, glancing at Sax. “We’re near the top of the viability atmosphere named in the Dorsa Brevia document.”
Nanao looked at Sax. “We want Sabishii under any limit that is set.”
Sax nodded, shrugged; he didn’t know what to say. The Reds would not like it. But if the viable altitude limit was raised a kilometer or so, it would give the Sabishiians this massif, and make little difference on the larger bulges— so it seemed to make sense. But who knew what they would decide on Pavonis? He said, “Maybe we should focus now on trying to keep atmospheric pressures from dropping.”
They looked somber.
Sax said, “You’ll take us out and show us the massif?”
They cheered up. “Most happy.”

The land of the Tyrrhena massif was what the areologists in the early years had called the “dissected unit” of the southern highlands, which was much the same as the “cratered unit,” but further broken by small channel networks. The lower and more typical highlands surrounding the massif also contained areas of “ridged unit” and “hilly unit.” In fact, as quickly became obvious the morning they drove out onto the land, all aspects of the rough terrain of the southern highlands were on view, often all at once: cratered, broken, uneven, ridged, dissected, and hilly land, the quintessential Noachian landscape. Sax and Nanao and Tariki sat on the observation deck of one of the Sabishii University rovers; they could see other cars carrying other colleagues, and there were teams out walking ahead of them. On the last hills before the horizon to the east, a few energetic people were fell-running. The hollows of the land were all lightly dusted with dirty snow. The massif was centered fifteen degrees south of the equator, and they got a fair bit of precipitation around Sabishii, Nanao said. The southeast side of the massif was drier, but here, the cloud masses pushed south over the ice in Isidis Planitia and climbed the slope and dropped their loads.
Indeed, as they drove uphill great waves of dark cloud rolled in from the northwest, pouring over them as if chasing the fell-runners. Sax shuddered, remembering his recent exposure to the elements; he was happy to be in a rover, and felt he would need only short walks away from it to be satisfied.
Eventually, however, they stopped on a high point in a low old ridge, and got out. They made their way over a surface littered with boulders and knobs, cracks, sand drifts, very small craters, breadloafed bedrock, scarps and alases, and the old shallow channels that gave the dissected unit its name. In truth there were deformational features of every kind to be seen, for the land here was four billion years old. A lot had happened to it, but nothing had ever happened to destroy it completely and clean the slate, so all four billion years were still there to be seen, in a veritable museum of rockscapes. It had been thoroughly pulverized in the Noachian, leaving regolith several kilometers deep, and craters and deformities that no aeolian stripping could remove. And during this early period the other side of the planet had had its lithosphere to a depth of six kilometers blasted into space by the so-called Big Hit; a fair amount of that ejecta had eventually landed in the south. That was the explanation for the Great Escarpment, and the lack of ancient highlands in the north; and one more factor in the extremely disordered look of this land.
Then also, at the end of the Hesperian had come the brief warm wet period, when water had occasionally run on the surface. These days most areologists thought that this period had been quite wet but not really very warm, annual averages of well under 273deg; Kelvin still allowing for surface water sometimes, replenished by hydrothermal convection rather than precipitation. This period had lasted for only a hundred million years or so, according to current estimates, and it had been followed by billions of years of winds, in the arid cold Amazonian Age, which had lasted right up to the point of their arrival. “Is there a name for the age starting with m-1?” Sax asked.
“The Holocene.”
And then lastly, everything had been scoured by two billion years of ceaseless wind, scoured so hard that the older craters were completely rimless, everything stripped at by the relentless winds strata by strata, leaving behind a wilderness of rock. Not chaos, technically speaking, but wild, speaking its unimaginable age in polyglot profusion, in rimless craters and etched mesas, dips, hummocks, escarpments, and oh so many blocky pitted rocks.
Often they stopped the rover and walked around. Even small mesas seemed to tower over them. Sax found himself staying near their rover, but nevertheless he came upon all kinds of interesting features. Once he discovered a rover-shaped rock, cracked vertically all the way through. To the left of the block, off to the west, he had a view to a distant horizon, the rocky land out there a smooth yellow glaze. To the right, the waist-high wall of some old fault, pocked as if by cuneiform. Then a sand drift bordered by ankle-high rocks, some of them pyramidal dark basaltic ventifacts, others lighter pitted granulated rocks. There a balanced shattercone, big as any dolmen. There a sand tail. There a crude circle of ejecta, like an almost completely weathered Stonehenge. There a deep snake-shaped hollow— the fragment of a watercourse, perhaps— behind it another gentle rise— then a distant prominence like a lion’s head. The prominence next to it was like the lion’s body.
In the midst of all this stone and sand, plant life was unobtrusive. At least at first. One had to look for it, to pay close attention to color, above all else to green, green in all its shades, but especially its desert shades— sage, olive, khaki, and so on. Nanao and Tariki kept pointing out specimens he hadn’t seen. Closer he looked, and closer again. Once attuned to the pale living colors, which blended so well with the ferric land, they began to jump out from the rust and brown and umber and ocher and black of the rockscape. Hollows and cracks were likely places to see them, and near the shaded patches of snow. The closer he looked, the more he saw; and then, in one high basin, it seemed there were plants tucked everywhere. In that moment he understood; it was all fellfield, the whole Tyrrhena massif.
Then, coating entire rockfaces, or covering the inside areas
of drip catchments, were the dayglow greens of certain lichens, and the emerald or dark velvet greens of the mosses. Wet fur.
The diversicolored palette of the lichen array; the dark green of pine needles. Bunched sprays of Hokkaido pines, foxtail pines, Sierra junipers. Life’s colors. It was somewhat like walking from one great roofless room to another, over ruined walls of stone. A small plaza; a kind of winding gallery; a vast ballroom; a number of tiny interlocked chambers; a sitting room. Some rooms held krummholz bansei against their low walls, the trees no higher than their nooks, gnarled by wind, cut along the top at the snow level. Each branch, each plant, each open room, as shaped as any bonsai— and yet effortless.
Actually, Nanao told him, most of the basins were intensively cultivated. “This basin was planted by Abraham.” Each little region was the responsibility of a certain gardener or gardening group.
“Ah!” Sax said. “And fertilized, then?”
Tariki laughed. “In a manner of speaking. The soil itself has been imported, for the most part.”
“I see.”
This explained the diversity of plants. A little bit of cultivation, he knew, had been done around Arena Glacier, where he had first encountered the fellfields. But here they had gone far beyond those early steps. Labs in Sabishii, Tariki told him, were trying their best to manufacture topsoil. A good idea; soil in fellfields appeared naturally at a rate of only a few centimeters a century. But there were reasons for this, and manufacturing soil was proving to be extremely difficult.
Still, “We pick up a few million years at the start,” Nanao said. “Evolve from there.” They hand-planted many of their specimens, it seemed, then for the most part left them to their fate, and watched what developed.
“I see,” Sax said.
He looked more closely yet. The clear dim light: it was true that each great open room displayed a slightly different array of species. “These are gardens, then.”
“Yes . . . or things like that. Depends.”
Some of the gardeners, Nanao said, worked according to the precepts of Muso Soseki, others according to other Japanese Zen masters; others still to Fu Hsi, the legendary inventor of the Chinese system of geomancy called-feng shui; others to Persian gardening gurus, including Omar Khayyam; or to Leopold or Jackson, or other early American ecologists, like the nearly forgotten biologist Oskar Schnelling; and so on.
These were influences only, Tariki added. As they did the work, they developed visions of their own. They followed the inclination of the land, as they saw that some plants prospered, and others died. Coevolution, a kind of epigenetic development.
“Nice,” Sax said, looking around. For the adepts, the walk from Sabishii up onto the massif must have been an aesthetic journey, filled with allusions and subtle variants of tradition that were invisible to him. Hiroko would have called it areoformation, or the areophany. “I’d like to visit your soil labs.”
“Of course.”
They returned to the rover, drove on. Late in the day, under dark threatening clouds, they came to the very top of the massif, which turned out to be a kind of broad undulating moor. Small ravines were filled with pine needles, sheered off by winds so that they looked like the blades of grass on a well-mowed yard. Sax and Tariki and Nanao again got out of the car, walked around. The wind cut through their suits, and the late-afternoon sun broke out from under the dark cloud cover, casting their shadows all the way out to the horizon. Up here on the moors there were many big masses of smooth bare bedrock; looking around, the landscape had the red primal look Sax remembered from the earliest years; but then they would walk to the edge of a small ravine, and suddenly be looking down into green.
Tariki and Nanao talked about ecopoesis, which for them was terraforming redefined, subtilized, localized. Transmuted into something like Hiroko’s areoformation. No longer powered by heavy industrial global methods, but by the slow, steady, and intensely local process of working on individual patches of land. “Mars is all a garden. Earth too for that matter. This is what humans have become. So we have to think about gardening, about that level of responsibility to the land. A human-Mars interface that does justice to both.”
Sax waggled a hand uncertainly. “I’m used to thinking of Mars as a kind of wilderness,” he said, as he looked up the etymology of the word garden. French, Teutonic, Old Norse, gard, enclosure. Seemed to share origins with guard, or keeping. But who knew what the supposedly equivalent word in Japanese meant. Etymology was hard enough without translation thrown into the mix. “You know— get things started, let loose the seeds, then watch it all develop on its own. Self-organizing ecologies, you know.”
“Yes,” Tariki said, “but wilderness too is a garden now. A kind of garden. That’s what it means to be what we are.” He shrugged, his forehead wrinkled; he believed the idea was true, but did not seem to like it. “Anyway, ecopoesis is closer to your vision of wilderness than industrial terraforming ever was.”
“Maybe,” Sax said. “Maybe they’re just two stages of a process. Both necessary.”
Tariki nodded, willing to consider it. “And now?”
“It depends on how we want to deal with the possibility of an ice age,” Sax said. “If it’s bad enough, kills off enough plants, then ecopoesis won’t have a chance. The atmosphere could freeze back onto the surface, the whole process crash. Without the mirrors, I’m not confident that the biosphere is robust enough to continue growing. That’s why I want to see those soil labs you have. It may be that industrial work on the atmosphere remains to be done. We’ll have to try some modeling and see.”
Tariki nodded, and Nanao too. Their ecologies were being snowed under, right before their eyes; flakes drifted down through the transient bronze sunlight at this very moment, tumbling in the wind. They were open to suggestion.
Meanwhile, as throughout these drives, their young associates from Da Vinci and Sabishii were running over the massif together, and returning to Sabishii’s mound maze babbling through the night about geomancy and areomancy, ecopoetics, heat exchange, the five elements, greenhouse gases, and so on. A creative ferment that looked to Sax very promising. “Michel should be here,” he said to Nanao. “John should be here. How he would love a group like this.”
And then it occurred to him: “Ann should be here.”
So he went back to Pavonis, leaving the group in Sabishii talking things over.
Back on Pavonis everything was the same. More and more people, spurred on by Art Randolph, were proposing that they hold a constitutional congress. Write an at least provisional constitution, hold a vote on it, then establish the government described.
“Good idea,” Sax said. “Perhaps a delegation to Earth as well.”
Casting seeds. It was just like on the moors; some would sprout, others wouldn’t.
He went looking for Ann, but found she had left Pavonis— gone, people said, to a Red outpost in Tempe Terra, north of Tharsis. No one went there but Reds, they said.
After some thought Sax asked for Steve’s help, and looked up the outpost’s location. Then he borrowed a little plane from the Bogdanovists and flew north, past Ascraeus Mons on his left, then down Echus Chasma, and past his old headquarters at Echus Overlook, on top of the huge wall to his right.
Ann too had no doubt flown this route, and thus gone by the first headquarters of the terraforming effort. Terraforming . . . there was evolution in everything, even in ideas. Had Ann noticed Echus Overlook, had she even remembered that small beginning? No way of telling. That was how humans knew each other. Tiny fractions of their lives intersected or were known in any way to anybody else. It was much like living alone in the universe. Which was strange. A justification for living with friends, for marrying, for sharing rooms and lives as much as possible. Not that this made people truly intimate; but it reduced the sensation of solitude. So that one was still sailing solo through the oceans of the world, as in Mary Shelley’s The Last Man, a book that had much impressed Sax as a youth, in which the e
ponymous hero at the conclusion occasionally saw a sail, joined another ship, anchored against a shore, shared a meal— then voyaged on, alone and solitary. An image of their lives; for every world was as empty as the one Mary Shelley had imagined, as empty as Mars had been in the beginning.
He flew past the blackened curve of Kasei Vallis without noting it at all.

The Reds had long ago hollowed out a rock the size of a city block, in a promontory that served as the last dividing wedge in the intersection of two of the Tempe Fossa, just south of Perepelkin Crater. Windows under overhangs gave them a view over both of the bare straight canyons, and the larger canyon they made after their confluence. Now all these fossae cut down what had become a coastal plateau; Mareotis and Tempe together formed a huge peninsula of ancient highlands, sticking far into the new ice sea.
Sax landed his little plane on the sandy strip on top of the promontory. From here the ice plains were not visible; nor could he spot any vegetation— not a tree, not a flower, not even a patch of lichen. He wondered if they had somehow sterilized the canyons. Just primal rock, with a dusting of frost. And nothing they could do about frost, unless they wanted to tent these canyons, to keep air out rather than in. “Hmm,” Sax said, startled at the idea.
Two Reds let him in the lock door on the top of the promontory, and he descended stairs with them. The shelter appeared to be nearly empty. Just as well. It was nice only to have to withstand the cold gazes of two young women leading him through the rough-hewn rock galleries of the refuge, rather than a whole gang. Interesting to see Red aesthetics. Very spare, as might be expected— not a plant to be seen— just different textures of rock: rough walls, rougher ceilings, contrasted to a polished basalt floor, and the glistening windows overlooking the canyons.
They came to a cliffside gallery that looked like a natural cave, no straighter than the nearly Euclidean lines of the canyon below. There were mosaics inlaid into the back wall, made of bits of colored stone, polished and set against each other without gaps, forming abstract patterns that seemed almost to represent something, if only he could focus properly on them. The floor was a stone parquet of onyx and alabaster, serpentine and bloodstone. The gallery went on and on— big, dusty— the whole complex somewhat disused, perhaps. Reds preferred their rovers, and places like this no doubt had been seen as unfortunate necessities. Hidden refuge; with windows shuttered, one could have walked down the canyons right past the place and not known it was there; and Sax felt that this was not just to avoid the notice of the UNTA, but also to be unobtrusive before the land itself, to melt into it.
