For Nirgal it was simple, and he regarded Coyote with some concern. “Art’s right. Hiroko will never forgive us if we start killing people for no reason.”
Coyote’s face twisted, as if in disgust for their softness. “We just killed a bunch of people in Kasei Vallis,” he said.
“But that was different!” Nirgal said.
“How so?”
Nirgal hesitated, unsure, and Art said quickly, “Those were a bunch of police torturers who had your buddy and were micro-waving his brain. They got what was coming to them. But these guys down this canyon are just digging up rocks.”
Sax nodded. He was staring at them all with the utmost intensity, and it seemed certain that he understood everything, and was deeply engaged in it; but mute as he was, it was hard to be sure.
Coyote stared hard at Art. “Is this a Praxis mine?”
“I don’t know. I don’t care, either.”
“Hmm. Well— ” Coyote looked at Sax; then at Spencer; then at Nirgal, who could feel his cheeks burning. “All right then. We’ll try it your way.”
And so at the end of the day Nirgal climbed out of the rover with Coyote and Art. The sky above was dark and starry, the western quadrant still purple, casting a florid light in which everything was quite visible but at the same time unfamiliar. Coyote led the way, and Art and Nirgal followed him closely. Through his faceplate Nirgal could see that Art’s eyes were pressing glass.
The floor of Tractus Catena was broken at one point by a transverse fault system called Tractus Traction, and the trellis fracturing in this zone had formed a system of crevasses impenetrable to vehicles. The Tractus miners reached their camp from the canyon wall above it, descending in elevators. But Coyote said it was possible to walk through Tractus Traction, following a path of connecting crevasses he had marked for himself. Many of his resistance actions involved crossing “impassable” terrain like this, making possible some of his more legendary impossible visitations, and sending him through badlands no one else had ever even approached. And with Nirgal to run some of the raids, they had performed some truly miraculous-seeming ventures — -just by getting out and traveling on foot.
So they jogged down the canyon floor, in the steady Martian lope that Nirgal had perfected, and had tried with partial success to teach to Coyote. Art was not graceful — his stride was too short, and he stumbled frequently — but he kept up. Nirgal began to feel the loose joy of running, the boulder ballet of it, the rapid crossing of long stretches of land under his own power. Also the rhythmic breathing, the bounce of his air tank on his back, the trancelike state that he had learned over the years, with help from the issei Nanao, who had been taught lung-gom on Earth by a Tibetan adept. Nanao claimed that some of the old lung-gom-pas had had to carry weights to keep from flying away, and on Mars it seemed entirely possible. The way he could fly over rocks was exhilarating, a kind of rapture.
He had to restrain himself. Neither Coyote nor Art knew lung-gom, and they couldn’t keep up, though they were both pretty good, Coyote for his age, Art for his recent arrival on Mars. Coyote knew the land, and ran in short mincing dance steps, efficient and clean. Art bombed over the landscape like a badly programmed robot, staggering often as he hit wrong in the starlight, but keeping up a pretty good head of steam nevertheless. Nirgal ranged in front of them like a dog. Twice Art went down in a cloud of dust and Nirgal ran over to check on him, but both times Art got up jogging, and in their intercom silence he only waved to Nirgal and ran on.
After half an hour’s run down the canyon, which was so straight that it seemed cut by design, cracks appeared on the ground, and quickly deepened and connected up with one another, until progress over the canyon floor proper would have been impossible, as it was now the plateau tops of a collection of islands. The deep slots separating these islands were in places only two or three meters wide, but thirty or forty meters deep.
Walking through these generally flat-floored alleys was a strange business, but Coyote led the way through the maze without delaying at any of the many forks, following a path only he knew, turning left and right a score of times. One slot was so narrow they could touch both walls at once, and they had to scrape through a turn.
When they came out the northern side of the crevasse maze, emerging from a draw in the riven steep escarpment which was the end of the plateau islands, a small tent stood before them against the western canyon wall. Its arc of fabric glowed like the bulb of a dusty lamp. Within the tent were mobile trailers, rovers, drills, earthmovers, and other mining equipment. It was a uranium mine, called Pitchblende Alley, because this lower section of the canyon was floored with a pegmatite extremely rich in uraninite. It was a very productive mine, and Coyote had heard that the processed uranium stockpiled at it during the years between elevators had not yet been shipped out.
Now Coyote ran over the canyon floor toward the tent, and Nirgal and Art followed. There was no one visible inside the tent; the only illumination was provided by a few night lights, and the lit windows of a big trailer set near the center of things.
Coyote walked right up to the tent’s nearest lock gate, and the other two followed him. He plugged his wristpad jack into the keyhole by the lock gate, and began to tap on his wristpad. The outer lock door opened. No alarms seemed to go off; no figures appeared out of the door of the trailer. They got in the lock, closed the outer door, waited for the lock to suck and pump, then opened the inner door. Coyote ran toward the settlement’s little physical plant, beside the trailer; Nirgal went for the living quarters, hopping up the steps to the trailer’s door. He held one of Coyote’s “locking bars” under the door handle, turned the dial that released the fixative, and pushed the bar against the door and wall of the trailer. The trailer was made of a magnesium-based alloy, and the polymer fixative would make what was in effect a ceramic bond between the locking bar and the trailer, so that the door would be stuck. He ran around the trailer and did the same to the other door, then dashed back toward the gate, feeling his blood fly through him as if it were pure adrenaline. It was so much like a prank that he had to consciously remember the explosive charges that Coyote and Art were distributing through the settlement, in warehouses, against the tent fabric, and in the parking lot for the mining behemoths. Nirgal joined them in running from vehicle to vehicle, climbing the stairs on their sides, opening doors manually or electronically, tossing small boxes Coyote had provided into the cabs or cabins.
But there were also hundreds of tons of processed uranium that Coyote wanted to haul away. This was impossible, unfortunately. They did run over to a warehouse, however, where they filled a number of the mine’s own robot trucks with loads, and programmed them with instructions to head off into the canyonlands to the north, burying loads in regions where the apatite concentrations might be high enough to disguise the boxed uranium’s radioactivity, and make the loads hard to relocate. Spencer had doubted this strategy would work, but Coyote said it beat leaving the uranium at the mine, and all of them were happy to help in any plan that would keep him from putting tons of uranium in the storage hold of their boulder car, radproof containers or not.
When that was done they ran back to the gate, and got back outside, and ran hard. Halfway to the escarpment they heard a series of pops and booms from the tent, and Nirgal glanced over his shoulder, but saw nothing different — the tent was still mostly d ^.rk, the trailer windows lit.
He turned and ran on, feeling as if he were flying, and was astonished to see Art racing over the canyon floor ahead of him, every stride a huge wild leap, bounding like some cheetah-bear all the way to the escarpment, where he had to wait for Coyote to catch up and lead them back through the crevasse maze. Once out of it he took off again, so fast that Nirgal decided to try to catch him, just to feel how fast it was. He got into the rhythm of the sprint, pressing harder and harder, and as he passed Art he saw that his own springbok strides were almost twice as long as Art’s even in sprint mode, where both their legs were pumping a
s fast as possible.
They got to the boulder car long before Coyote, and waited for him in the lock, catching their breath, grinning through their faceplates at each other. A few minutes later Coyote was there and in with them, and Spencer had the rover moving, with the timeslip just past, and six more hours of night to drive in.
Inside they laughed hard at Art’s mad run, but he only grinned and waved them off. “I wasn’t scared, it’s this Martian gravity I tell you, I was just running the way I usually would but my legs were leaping along like a tiger! Amazing.”
They rested through the day, and after dark they were off again. They passed the mouth of a long canyon that ran from Ceraunius to Jovis Tholus; it was an oddity in that it was neither straight nor sinuous, and was called Crooked Canyon. When the sun rose they were hidden on the apron of Crater Qr, just north of Jovis Tholus. Jovis Tholus was a bigger volcano than Tharsis Tholus, bigger in fact than any volcano on Earth, but it was located on the high saddle between Ascraeus Mons and Olympus Mons, and both were visible on skysills to east and west, bulking like vast plateau continents, and making Jovis seem compact, friendly, comprehensible — a hill you could walk up if you wanted to.
That day Sax sat and stared silently at his screen, tapping at it tentatively and getting a random assortment of texts, maps, diagrams, pictures, equations. He tilted his head at each, with no sign of recognition. Nirgal sat down beside him. “Sax, can you hear what I’m saying?”
Sax looked at him.
“Can you understand my words? Nod if you understand.”
Sax tilted his head to the side. Nirgal sighed, held by that inquisitive look. Sax nodded, hesitantly.
That night Coyote drove west again, toward Olympus, and near dawn he directed the rover right up to a wall of pocked and riven black basalt. This was the edge of a tableland cut by innumerable narrow twisting ravines, like Tractus Traction only on a much larger scale, creating a badlands like an immense expansion of the Traction’s maze. The tableland was a fan of broken ancient lava, the remnant of one of the earliest flows from Olympus Mons, capping softer tuff and ash from even earlier eruptions. Where the wind-cut ravines had worn deep enough, their bottoms broke through into the layer of softer tuff, so that some ravines were narrow slots with tunnels at their bottoms, rounded by eons of wind. “Like upside-down keyholes,” Coyote said, though Nirgal had never seen a keyhole remotely like these shapes.
Coyote drove the rover right into one of the black-and-gray tunnel ravines. Several kilometers up the tunnel he stopped the car, beside a wall of tenting that cut off a kind of embolism in the tunnel, a widened outer curve.
This was the first hidden sanctuary that Art had ever seen, and he looked suitably startled. The tent was perhaps twenty meters tall, containing a section of the curve a hundred meters long; Art exclaimed over the size of it until Nirgal had to laugh. “Someone else is already here using it,” Coyote said, “so be quiet for a second.”
Art nodded quickly, and leaned over Coyote’s shoulder to hear what he was saying over the intercom. Parked before the tent lock was another car, just as lumpish and rocky as their own. “Ah,” said Coyote, pushing Art back. “It’s Vijjika. They’ll have oranges, and maybe some kava. We’ll have a party this morning for sure.”
They rolled up to the tent lock, and a coupler tube reached out and clamped around their exterior door. When all the lock doors were opened they made their way into the tent, bending and shuffling to carry Sax through the tube with them.
They were met inside by eight tall, dark-skinned people, five women and three men — a loud group, happy to have company. Coyote introduced them all, although Nirgal knew Vijjika from the university in Sabishii, and gave her a big hug. She was pleased to see him again, and led them all back to the smooth curve of the cliff wall, into a clearing between trailers, under a skylight provided by a vertical crack in the old lava. Under this shaft of diffuse daylight, and the even more diffuse light from the deep ravine outside the tent, the visitors sat on broad flat pillows around low tables, while several of their hosts went to work at a clutch of round-bellied samovars. Coyote was talking with acquaintances, catching up on the news. Sax looked around, blinking, and Spencer, beside him, did not look much less confused; he had been living in the surface world since ‘61, and his knowledge of the sanctuaries must have been almost entirely secondhand. Forty years of a double life; it was no wonder he looked stunned.
Coyote went to the samovars, and began handing out tiny cups from a freestanding cabinet. Nirgal sat next to Vijjika, an arm around her waist, soaking in her warmth and buzzing with the long contact of her leg against his. Art sat down on her other side, his broad face thrust into the conversation like a dog’s. Vijjika introduced herself to him, and shook his hand; he clasped her long delicate fingers in his big paw as if he wanted to kiss them. “These are Bogdanovists,” Nirgal explained to Art, laughing at. his expression and handing him one of the little ceramic cups from Coyote. “Their parents were prisoners in Korolyov before the war.”
“Ah,” Art said. “We’re a long way from there, right?”
Vijjika said, “Yes, well, our parents took the Transmarineris Highway north, just before it was flooded, and eventually they came here. Here, take that tray from Coyote and go pass out cups, and introduce yourself to everyone.”
So Art made the rounds, and Nirgal caught up on news with Vijjika. “You won’t believe what we’ve found in one of these tuff tunnels,” she told him. “We’ve become most fantastically rich.” Everyone had their cup, so they all paused for a moment and took their first sips together, then after some whoops and a general smacking of the lips they went back to their conversations. Art returned to Nirgal’s side.
“Here, have some yourself,” Nirgal told him. “Everyone needs to join the toast, that’s the way they do it.”
Art took a sip from his cup, looking dubious at the liquid, which was blacker than coffee, and foul-smelling. He shuddered. “It’s like coffee with licorice mixed into it. Poisoned licorice.”
Vijjika laughed. “It’s kavajava,” she said, “a mixture of kava and coffee. Very strong, and it tastes like hell. And hard to come by. But don’t give up on it. If you can get a cup down you’ll find it’s worth it.”
“If you say so.” Manfully he downed another swallow, shuddering again. “Horrible!”
“Yes. But we like it. Some people just extract the kavain from the kava, but I don’t think that’s right. Rituals should have some unpleasantness, or you don’t appreciate them properly.”
“Hmm,” Art said. Nirgal and Vijjika watched him. “I’m in a refuge of the Martian underground,” he said after a while, “Getting high on some weird awful drug, in the company of some of the most famous lost members of the First Hundred. As well as young natives never known to Earth.”
“It’s working,” Vijjika observed.
Coyote was talking to a woman, who, though sitting in the lotus position on one of the pillows, was just below his eye level as he stood before her. “Sure I’d like to have romaine lettuce seeds,” the woman said. “But you have to take fair for something so valuable.”
“They’re not that valuable,” Coyote said in his plausible style. “You’re already giving us more nitrogen than we can burn.”
“Sure, but you have to get nitrogen before you can give it.”
“I know that.”
“Get before you give, and give before you burn. And here we’ve found this enormous vein of sodium nitrate, it’s pure caliche blanco, and these badlands are stuffed with it. It looks like there’s a band of it between the tuff and the lava, about three meters thick and extending, well, we don’t even know how far yet. It’s a huge amount of nitrogen, and we’ve got to get rid of it.”
“Fine, fine,” Coyote said, “but that’s no reason to start potlatch-ing on us.”
“We’re not potlatching. You’re going to bum eighty percent of what we give you—”
“Seventy.”
“Oh
yeah, seventy, and then we’ll have these seeds, and we’ll finally be able to eat decent salads with our meals.”
“If you can get them to grow. Lettuce is delicate.”
“We’ll have all the fertilizer we need.”
Coyote laughed. “I guess so. But it’s still out of whack. Tell you what, we’ll give you the coordinates for one of those trucks of uranium we sent off into Ceraunius.”
“Talk about potlatching!”
“No no, because there’s no guarantee that you’ll be able to recover the stuff. But you’ll know where it is, and if you do recover it, then you can just burn another picobar of nitrogen, and we’ll be even. How about that?”
“It still seems like too much to me.”
“You’re going to be feeling like that all the time with this caliche blanco you’ve found. There’s really that much of it?”
“Tons of it. Millions of tons of it. These badlands are layered through and through with it.”
“All right, maybe we can get some hydrogen peroxide from you too. We’re going to need the fuel for the trip south.” ~~~Art leaned toward them as if pulled by a magnet. “What’s caliche blancol”
“It’s nearly pure sodium nitrate,” the woman said. She described the areology of the region. Rhyolitic tuff — the light-colored rock surrounding them — had been overlaid by the dark andesite lava that roofed the tableland. Erosion had carved the tuff wherever bracks in the andesite exposed it, forming the tunnel-bottomed ravines, and also revealing great seams of caliche, trapped between the two layers. “The caliche is loose rock and dust, cemented together with salts and the sodium nitrates.”
“Microorganisms must have laid that layer down,” a man beyond the woman said, but she instantly disagreed:
“It could have been areothermal, or lightning attracted ,by the quartz in the tuff.”
They argued in the way people do when they are repeating a debate for the thousandth time. Art interrupted to ask again about the caliche blanco. The woman explained that blanco was a very pure caliche, up to eighty percent pure sodium nitrate, and thus, on this nitrogen-poor world, extremely valuable. A block of it sat on the table, and she passed it over to Art and went back to arguing with her friend, while Coyote bartered on with another man, talking about teeter-totters and pots, kilograms and calories, equivalence and overburden, cubic meters per second and picobars, haggling expertly and getting a lot of laughs from the people listening.
