Green Mars - Kim Stanley Robinson [77]
Burroughs’ old canal park, and the broad grass boulevards that climbed away from the park and between the mesas, were now strips of green, cutting through orange tile rooftops. The old double row of salt columns still stood beside the blue canal. There had been a lot of building, to be sure; but the configuration of the city was still the same. It was only on the outskirts that one could see clearly how much things had changed, and how much larger the city really was; the city wall lay well beyond the nine mesas, so that quite a bit of surrounding land was sheltered, and much of it built upon already.
The personnel secretary gave Sax a quick tour of Biotique, making introductions to more people than he could remember. Then Sax was asked to report to his lab the next morning, and given the rest of the day to get settled in.
As Stephen Lindholm he planned to exhibit signs of intellectual energy, sociability, curiosity, and high spirits; and so he very plausibly spent that afternoon exploring Burroughs, wandering from neighborhood to neighborhood. He strolled up and down the wide swards of streetgrass, considering as he did the mysterious phenomenon of the growth of cities. It was a cultural process with no very good physical or biological analogy. He could see no obvious reason why this low end of Isidis Planitia should have become home to the largest city on Mars. None of the original reasons for siting the city here were at all adequate to explain it; so far as he knew, it had begun as an ordinary way station on the piste route from Elysium to Tharsis. Perhaps it was precisely because of its lack of strategic location that it had prospered, for it had been the only major city not damaged or destroyed in 2061, and thus perhaps it simply had had a head start on growth in the postwar years. By analogy to the punctuated equilibrium model of evolution, one might say that this particular species had accidentally survived an impact that had devastated most other species, giving it an open ecosphere to expand in.
And no doubt the bowllike shape of the region, with its archipelago of small mesas, gave it an impressive look as well. When he walked around on the wide grassy boulevards, the nine mesas appeared evenly distributed, and each mesa had a slightly different look, its rugged rock walls distinguished by characteristic knobs, buttresses, smooth walls, overhangs, cracks— and now the horizontal bands of colorful mirror windows, and the buildings and parks on the flat plateaus crowning each mesa. From any point on the streets one could always see several of the mesas, scattered like magnificent neighborhood cathedrals, and this no doubt gave a certain pleasure to the eye. And then if one took an elevator up to one of the mesa’s plateau tops, all about a hundred meters higher than the city floor, then one had a view over the rooftops of several different districts, and a different perspective on the other mesas, and then, beyond those, the land surrounding the city for many kilometers, distances larger than were usual on Mars, because they were at the bottom of a bowl-shaped depression: over the flat plain of Isidis to the north, up the dark rise to Syrtis in the west, and to the south one could see the distant rise of the Great Escarpment itself, standing on the horizon like a Himalaya.
Of course whether a handsome prospect mattered to city formation was an open question, but there were historians who asserted that many ancient Greek cities were sited principally for their view, in the face of other inconveniences, so it was at least a possible factor. And in any case Burroughs was now a bustling little metropolis of some 150,000 people, the biggest city on Mars. And it was still growing. Near the end of his afternoon’s sightseeing, Sax rode one of the big exterior elevators up the side of Branch Mesa, centrally located north of Canal Park, and from its plateau he could see that the northern outskirts of town were studded with construction sites all the way to the tent wall. There was even work going
