Green mars (57 page)

“Oh. Well, some say we’re Booneans, or a kind of Marsfirst wing. I don’t think that’s right. I don’t name it, myself. Maybe Ka. Or Free Mars. We say that, as a kind of greeting. Verb, noun, whatever. Free Mars.”

“Hmm,” Maya said, feeling the chill humid wind on her cheek, Nirgal’s arm around her waist. An alternative economy, functioning without the rule of law, was intriguing but dangerous; it could turn into a black economy run by gangsters, and there was very little that any idealistic village could do about it. So that as a solution to the Transitional Authority it was somewhat illusory, she judged.

But when she expressed these reservations to Nirgal, he agreed. “I don’t think of this as the final step. But I think it helps. It’s what we can do now. And then, when the time comes ...”

Maya nodded in the darkness. It was another Creche Crescent, she thought suddenly. They walked back up to the village together, where the party was still going on. There five young women at least began jockeying to be the last one at Nirgal’s side when the party ended, and with a laugh only slightly edged (if she were young they would not have had a chance) Maya left them to it and went to bed.

After two days’ driving downstream from the market village, still forty kilometers from Hell’s Gate, they came around a bend in the canyon and could see down the length of it, to the towers of the piste’s suspension bridge. Like something out of a different world, Maya thought, with a different technology entirely. The towers were six hundred meters high, and ten kilometers apart—a truly immense bridge, dwarfing the town of Hell’s Gate itself, which did not roll over the horizon for another hour, and then came visible from the rim downward, its buildings spilling down the steep canyon walls like some dramatic seafront village in Spain or Portugal—but all in the shadow of the enormous bridge. Enormous, yes—and yet there were bridges twice as big as it in Chryse, and with the continual improvements in materials, there was no end in sight. The new elevator cable’s carbon nanotube filament had a tensile strength that was overkill even for the elevator’s needs, and using it you could build just about any surface bridge you could possibly imagine; people spoke of bridging Marineris, and there were jokes about running cable car lines between the prince volcanoes on Tharsis, to save people the fifteen-kilometer vertical drops between the three peaks.

Back in Hell’s Gate Maya and Diana returned the car to the garage, and had a big dinner in a restaurant about halfway up the wall of the valley, under the bridge. After that Diana had friends she wanted to see, so Maya excused herself and went to the Deep Waters offices, and her room. But outside the glass doors of her room, above its little balcony, the great span of the bridge arched through the stars, and remembering Dao Canyon and its people, and black Hadriaca ribboned white with its snow-filled channels, she had great difficulty getting to sleep. She went out and sat curled in a blanket, on a chair on her balcony, for a good part of the night, watching the underside of the giant bridge and thinking about Nirgal and the young natives, and what they meant.

The
 
next
 
morning they were
 
supposed
 
to
 
take the
 
next circumHellas train, but Maya asked Diana to drive her out onto the basin floor instead, to see in person what happened to the water running down the Dao River. Diana was happy to oblige.

At the lower end of the town, the stream poured into a narrow reservoir, dammed by a thick concrete dam and pump, located right at the tent wall. Outside the tent, water was carried off across the basin in a fat insulated pipeline, set on three-meter pylons. The pipeline ran down the broad gentle eastern slope of the basin, and they followed it in another company rover, until the crumbled cliffs of Hell’s Gate disappeared over the low dunes of the horizon behind them. An hour later the towers of the bridge were still visible, poking up over the skyline.

A few kilometers farther on, the pipeline ran out over a reddish plain of cracked ice—a kind of glacier, except that it fanned out right to left over the plain for as far as they could see. It was the current shore of their new sea, in fact, or at least one lobe of it, frozen in its place. The pipeline ran out over the ice, then descended into it, disappearing a couple of kilometers from shore.

A small, nearly submerged crater ring stuck out into the ice like a curving double peninsula, and Diana followed tracks onto one peninsula and drove until they were as far out in the ice as they could get. The visible world before them was completely covered with ice; behind them lay the rising slope of sand. “This lobe extends out a long way now,” Diana said. “Look there—” She pointed at a silver twinkling on the western horizon.

Maya took a pair of binoculars from the dash. On the horizon she could make out what appeared to be the northern edge of the lobe of ice, where it gave way again to rising sand dunes. As she watched, a mass of ice at this border toppled, looking like a Greenland glacier caving into the sea, except that when it hit the sand it shattered into hundreds of white pieces. Then there was a spill of water, running as dark as the Ruby River out over the sand. Dust dashed up and away from this stream, and blew south on the wind. The edges of the new flow began to whiten, but Maya saw that it was nothing like the frightening speed with which the flood in Marineris had frozen in ‘61. It stayed liquid, with hardly any frost steam, for minute after minute, right out there in the open air! Oh the world was warmer, all right, and the atmosphere thicker; up to 260 millibars sometimes down here in the basin, and the temperature outside at the moment was 271°K. A very pleasant day! She surveyed the surface of the ice lobe through the binoculars, and saw that it was liberally dotted by the bright white sheens of meltwater ponds that had refrozen clean and flat.

“Things are changing,” Maya said, although not to Diana; and Diana did not reply.

Eventually the flood of new dark water whitened all over its surface, and stopped moving. “It’s coming out somewhere else now,” Diana said. “It works like sedimentation in a river delta. The main channel for this lobe is actually well to the south of here.”

“I’m glad I saw this. Let’s get back.”

They drove back to Hell’s Gate, and that night had supper together again, on the same restaurant terrace under the great bridge. Maya asked Diana a great number of questions about Paul and Esther and Kasei and Nirgal and Rachel and Emily and Reull and the rest of Hiroko’s brood, and their children and their children’s children. What were they doing now? What were they going to do? Did Nirgal have lots of followers?

“Oh yes, of course. You saw how it is. He travels all the time, and there’s a whole network of natives in the northern cities who take care of him. Friends, and friends of friends, and so on.”

“And you think these people will support a ...”

“Another revolution?”

“I was going to say independence movement.”

“Whatever you call it, they’ll support it. They’ll support Nirgal. Earth looks like a nightmare to them, a nightmare trying to drag us down into it. They don’t want that.”

“They?” Maya said, smiling. .
 
“Oh me too.” Diana smiled back. “Us.”

As they continued clockwise around Hellas, Maya had cause to remember that conversation. A consortium from Elysium, without any metanat or UNTA connections that Maya could discover, had just finished roofing over the Harmakhis-Reull valleys, using the same method that had been used to roof Dao. Now there were hundreds of people in those two linked canyons, outfitting the aerators and working up soils, and seeding and planting the nascent biosphere of the canyons’ mesocosm. Their on-site greenhouses and manufacturing plants were producing much of what they needed for this work, and metals and gases were being mined out of the badlands of Hesperia to the east, and brought into the town at the mouth of Harmakhis Vallis called Sukhumi. These people had the starter programs and the seeds, and they did not appear to put much stock in the Transitional Authority; they had not asked permission from it to engage in their project, and they actively disliked the official crews from the Black Sea Group, who were usually Terran metanat representatives.

They were hungry for manpower, however, and were happy to get more technicians.or generalists from Deep Waters, and any equipment they could cadge from its headquarters. Practically every group Maya met in the Harmakhis-Reull region made a pitch for aid, and most of them were young natives, who seemed to think they had just as much chance at the equipment as anyone else, even though they were not affiliated with Deep Waters or any other company.

And everywhere south of Harmakhis-Reull, in the ragged ejecta hills behind the rim of the basin, there were dowsing crews’, out looking for aquifers. As in the roofed canyons, most of these crews had been born on Mars, and a .lot of them had been born on Mars since ‘61. And they were different, profoundly different, sharing interests and enthusiasms perfectly incommunicable to any other generation, as if genetic drift or disruptive selection had produced a bimodal distribution, so that members of the old Homo sapiens were now coinhabiting the planet with a new Homo ares, creatures tall and slender and graceful and utterly at home, chattering to each other in a profound self-absorption as they did the work that would make Hellas Basin into a sea.

And this gigantic project was perfectly natural work to them.’ At one stop on the piste Maya and Diana got out and drove with some friends of Diana’s out onto one of the ridges of the Zea Dorsa, which ran out onto the southeast quarter of the basin floor. Now most of these dorsa were peninsulas running out under another ice lobe, and Maya looked down at the crevasse-riven glaciers to each side and tried to imagine a time when the surface of the sea would in fact lie hundreds of meters overhead, so that these craggy old basalt ridges would be nothing but blips on some ship’s sonar, home to starfish and shrimp and krill and extensive varieties of engineered bacteria. That time was not far off, amazing though it was to realize it. But Diana and her friends, these in particular of Greek ancestry, or was it Turkish—these young Martian dowsers were not awed by this imminent future, nor by their project’s vast-ness. It was their work, their life—to them it was human scale, there was nothing unnatural about it. On Mars, simply enough, human work consisted of pharaonic projects like this one. Creating oceans. Building bridges that made the Golden Gate look like a toy. They weren’t even watching this ridge, which would only be visible for a while longer—they were talking about other things, mutual friends in Sukhumi, that sort of thing.

“This is a stupendous act!” Maya told them sharply. “This is magnitudes bigger than anything people have been able to do before! This sea is going to be the size of the Caribbean! There’s never been any project anything like this on Earth—no project! Not even close!”

A pleasant oval-faced woman with beautiful skin laughed. “I don’t give a damn about Earth,” she said.

The new piste curved around the southern rim, crossing transversely some steep ridges and ravines which were called the Axius Valles. These corrugations ran from the rim’s rough hills down into the basin, forcing the piste viaduct to alternate between great arching bridges and deep cuts, or tunnels. The train they had boarded after the Zea Dorsa was a short private one belonging to the Odessa office, so Maya got it to stop at most of the small stations along this stretch, and she got out to meet and talk with the dowsing and construction crews. At one stop they were all Earthbom emigrants, and to Maya much more comprehensible than the blithe natives—normal-sized people, staggering around amazed and enthusiastic, or dismayed and complaining, in any case aware of how strange their enterprise was. They took Maya down a tunnel in a ridge, and it turned out that the ridge was a lava tunnel running down from Am-phitrites Patera, its cylindrical cavity much the same size as Dorsa Brevia’s, but tilted at a sharp angle. The engineers were pumping the Amphitrites aquifer’s water into it, and using it as their pipeline to the basin floor. So now, as the grinning Earthborn hydrologists showed her as she stepped into an observation gallery cut into the side of the lava tube, black water was racing down the bottom of the huge tunnel, barely covering its bottom even at 200 cubic meters a second, the roar of its splashing echoing in the empty cylinder of basalt. “Isn’t it great?” the emigrants demanded, and Maya nodded, happy to be with people whose reactions she could understand. “Just like a damn big storm dram, isn’t it?”

But back at the train, the young natives nodded at Maya’s exclamations—lava tube pipeline, of course—very big, yes, it would be wouldn’t it—saved her some pipe for the less fortunate operations, yes? And then they went back to discussing some people they knew that Maya had never heard of.

As the train continued they rounded the southwest arc of the basin, and the piste led them north. They rode over four or five more big pipelines, snaking out of high canyons in the Hellespontus Monies to their left, canyons between bare serrated ridges of rock, like something out of Nevada or Afghanistan, the peaks whitened with snow. Out the windows to the right, down on the basin floor, there were more spreading patches of dirty broken ice, often marked by the flat white patches of newer spills. They were building on the hilltops by the piste, little tent towns like places out of the Tuscan Renaissance. “These foothills will be a popular place to live,” Maya said to Diana. “They’ll be between the mountains and the sea, and some of these canyon mouths should end up as little harbors.”
