vote, but this was turned down as endangering the tenuous grasp they had on representative governance. It would have made no difference anyway.

      So they voted to allow the space elevator to remain standing, for the time being – and in the possession of UNTA, down to and including the Socket, without contestation. It was like King Canute deciding to declare the tide legal after all, but no one laughed except Ann. The other Reds were furious. Ownership of the Socket was still being actively contested, Dao objected loudly, the neighbourhood around it was vulnerable and could be taken, there was no reason to back off like this, they were only trying to sweep a problem under the rug because it was hard! But the majority were in agreement. The cable should remain.

      Ann felt the old urge: escape. Tents and trains, people, the little Manhattan skyline of Sheffield against the south rim, the summit basalt all torn and flattened and paved over … There was a piste all the way around the rim, but the western side of the caldera was very nearly uninhabited. So Ann got in one of the smallest Red rovers, and drove around the rim counterclockwise, just inside the piste, until she came to a little meteorological station, where she parked the rover and went out through its lock, stiff in a walker that was much like the ones they had gone out in during the first years.

      She was a kilometre or two away from the rim’s edge. She walked slowly east toward it, stumbling once or twice before she started to pay proper attention. The old lava on the flat expanse of the broad rim was smooth and dark in some places, rough and lighter in others. By the time she approached the edge she was in full areologist mode, doing a boulder ballet she could sustain all day, attuned to every knob and crack underfoot. And this was a good thing, because near the rim’s drop-off the land collapsed in a series of narrow curving ledges, the drops sometimes a step, sometimes taller than she was. And always the growing sense of empty air ahead, as the far side of the caldera and the rest of the great circle became visible. And then she was climbing down onto the last ledge, a bench only some five metres wide, with a curved back wall, shoulder-high: and below her dropped the great round chasm of Pavonis.

      This caldera was one of the geological marvels of the solar system, a hole forty-five kilometres across and a full five kilometres deep, and almost perfectly regular in every way – circular, flat-floored, almost vertically walled – a perfect cylinder of space, cut into the volcano like a rock sampler’s coring. None of the other three big calderas even approached this simplicity of form; Ascraeus and Olympus were complicated palimpsests of overlapping rings, while the very broad, shallow caldera of Arsia was roughly circular, but shattered in every way. Pavonis alone was a regular cylinder: the Platonic ideal of a volcanic caldera.

      Of course from this wonderful vantage point she now had, the horizontal stratification of the interior walls added a lot of irregular detail, rust and black and chocolate and umber bands indicating variations in the composition of the lava deposits; and some bands were harder than those above and below, so that there were many arcuate balconies lining the wall at different elevations – isolated curving benches, perched on the side of the immense rock throat, most never visited. And the floor so flat. The subsidence of the volcano’s magma chamber, located some one hundred and sixty kilometres below the mountain, had to have been unusually consistent; it had dropped in the same place every time. Ann wondered if it had been determined yet why that had been; if the magma chamber had been younger than the other big volcanoes, or smaller, or the lava more homogenous … Probably someone had investigated the phenomenon; no doubt she could look it up on the wrist. She tapped out the code for the Journal of Areological Studies, typed in Pavonis: ‘Evidence of Strombolian explosive activity found in west Tharsis clasts’. ‘Radial ridges in caldera and concentric graben outside the rim suggest late subsidence of the summit’. She had just crossed some of those graben. ‘Release of juvenile volatiles into atmosphere calculated by radiometric dating of Lastflow marks’.

      She clicked off the wristpad. She no longer kept up with all the latest areology, she hadn’t for years. Even reading the abstracts would have taken far more time than she had. And of course a lot of areology had been badly compromised by the terraforming project. Scientists working for the metanats had concentrated on resource exploration and evaluation, and had found signs of ancient oceans, of the early warm wet atmosphere, possibly even of ancient life; on the other hand radical Red scientists had warned of increased seismic activity, rapid subsidence, mass wasting, and the disappearance of even a single surface sample left in its primal condition. Political stress had skewed nearly everything written about Mars in the past hundred years. The Journal was the only publication Ann knew of which tried to publish papers delimiting their inquiries very strictly to reporting areology in the pure sense, concentrating on what had happened in the five billion years of solitude; it was the only publication Ann still read, or at least glanced at, looking through the titles and some of the abstracts, and the editorial material at the front; once or twice she had even sent in a letter concerning some detail or other, which they had printed without fanfare. Published by the university in Sabishii, the Journal was peer-reviewed by like-minded areologists, and the articles were rigorous, well-researched and with no obvious political point to their conclusions; they were simply science. The journal’s editorials advocated what had to be called a Red position, but only in the most limited sense, in that they argued for the preservation of the primal landscape so that studies could be carried on without having to deal with gross contaminations. This had been Ann’s position from the very start, and it was still where she felt most comfortable; she had moved from that scientific position into political activism only because it had been forced on her by the situation. This was true for a lot of areologists now supporting the Reds. They were her natural peer group, really – the people she understood, and with whom she sympathized.

      But they were few; she could almost name them individually. The regular contributors to the Journal more or less. As for the rest of the Reds, the Kakaze and the other radicals, what they advocated was a kind of metaphysical position, a cult – they were religious fanatics, the equivalent of Hiroko’s Greens, members of some kind of rock-worshipping sect. Ann had very little in common with them, when it came down to it; they formulated their Redness from a completely different worldview.

      And given that there was that kind of fractionization among the Reds themselves, then what could one say about the Martian independence movement as a whole? Well. They were going to fall out. It was happening already.

      Ann sat down carefully on the edge of the final bench. A good view. It appeared there was a station of some kind down there on the caldera floor, though from five thousand metres up, it was hard to be sure. Even the ruins of old Sheffield were scarcely visible – ah – there they were, on the floor under the new town, a tiny pile of rubble with some straight lines and plane surfaces in it. Faint vertical scorings on the wall above might have been caused by the fall of the city in ’61. It was hard to say.

      The tented settlements still on the rim were like toy villages in paperweights. Sheffield with its skyline, the low warehouses across from her to the east, Lastflow, the various smaller tents all around the rim … many of them had merged, to become a kind of greater Sheffield, covering almost 180° of the rim, from Lastflow around to the southwest, where pistes followed the fallen cable down the long slope of west Tharsis to Amazonis Planitia. All the towns and stations would always be tented, because at twenty-seven kilometres high the air would always be a tenth as thick as it was at the datum – or sea level, one could now call it. Meaning the atmosphere up here was still only thirty or forty millibars thick.

      Tent cities forever; but with the cable (she could not see it) spearing Sheffield, development would certainly continue, until they had built a tent city entirely ringing the caldera, looking down into it. No doubt they would then tent the caldera itself, and occupy the round floor – add about fifteen hundred square kilometres to the city, though it was a question who would want to live at the bottom of such a hole, like living at the bottom of a mohole, rock walls rising up around you as if you were in some circular roofless cathedral … perhaps it would appeal to some. The Bogdanovists had lived in moholes for years, after all. Grow forests, build climbers’ huts or rather millionaires’ penthouses on the arcuate balcony ledges, cut staircases into the sides of the rock, install glass elevators that took all day to go up or down … rooftops, terraces,
