Green Mars - Kim Stanley Robinson [24]
“Okay,” Nirgal said, afraid.
“As for how long we will have to stay hiding, I think it will be forever.”
They drove back south to Rayleigh mohole, where Coyote (he didn’t seem to be a Desmond) had thought to go in the first place. This mohole was truly abandoned, an unlit hole in the highlands, its thermal plume standing over it like the ghost of a monument. They could drive right into the empty sand-covered parking lot and garage at its rim, between a small fleet of robot vehicles shrouded by tarpaulins and sand drifts. “This is more like it,” Coyote muttered. “Here, we’ve got to take a look down inside it. Come on, get into your walker.”
It was strange to be out in the wind, standing on the rim of such an enormous gap in things. They looked over a chest-high wall and saw the beveled concrete band that rimmed the hole, dropping at an angle for about two hundred meters. In order to see down the shaft proper, they had to walk about a kilometer down a curving road cut into the concrete band. There they could stop at last, and look over the road’s edge, down into blackness. Coyote stood right on the edge, which made Nirgal nervous. He got on his hands and knees to look over. No sign of a bottom; they might as well have been looking into the center of the planet. “Twenty kilometers,” Coyote said over the intercom. He held a hand out over the edge, and Nirgal did too. He could feel the updraft. “Okay, let’s see if we can get the robots going.” And they hiked back up the road.
Coyote had spent many of their daytime hours studying old programs on his AI, and now, with the hydrogen peroxide from their trailer pumped into two of the robot behemoths in the parking lot, he plugged into their control panels and went at it. When he was done he was satisfied they would perform as required at the bottom of the mohole, and they watched the two, with wheels four times as tall as Coyote’s car, roll off down the curving road.
“All right,” Coyote said, cheering up again. “They’ll use their solar-panel power to process their own peroxide explosives, and their own fuel as well, and go at it slow and steady until maybe they hit something hot. We just may have started a volcano!”
“Is that good?”
Coyote laughed wildly. “I don’t know! But no one’s ever done it before, so it has that at least to recommend it.”

They returned to their scheduled travel, among sanctuaries both hidden and open, and Coyote went around saying, “We started up Rayleigh mohole last week, have you seen a volcano yet?”
No one had seen it. Rayleigh seemed to be behaving much as before, its thermal plume undisturbed. “Well, maybe it didn’t work,” Coyote would say. “Maybe it will take some time. On the other hand if that mohole was now floored with molten lava, how would you be able to tell?”
“We could tell,” people said. And some added: “Why would you do something as stupid as that? You might as well call up the Transitional Authority and tell them to come down here to look for us.”
So Coyote stopped bringing it up. They rolled on from sanctuary to sanctuary: Mauss Hyde, Gramsci, Overhangs, Christianopolis. . . . At each stop Nirgal was made welcome, and often people knew of him in advance, by reputation. Nirgal was very surprised by the variety and number of sanctuaries, forming together their strange world, half secret and half exposed. And if this world was only a small part of Martian civilization as a whole, what must the surface cities of the north be like? It was beyond his grasp— although it did seem to him that as the marvels of the journey continued, one after the next, his grasp was getting a bit larger. You couldn’t just explode from amazement, after all.
“Well,” Coyote would say as they drove (he had taught Nirgal how), “we may have started a volcano and we may not have. But it was a new idea in any case. That’s one of the greatest things about this, boy, this whole Martian project.
