It was near midsummer, and the sun rode the sky all day long. Clouds poured off the ice to the north. When the sun was at its lowest, the equivalent of midafternoon, these clouds drifted south toward the sea in thick mists, colored bronze or purple or lilac or some other vibrant subtle shade. A thin scattering of fellfield flowers graced the laminate plateau, reminding Sax of Arena Glacier, the landscape that had first caught his attention, back before his incident. That first encounter was very difficult for Sax to remember, but apparently it had imprinted on him in the way ducklings imprinted on the first creatures they saw as their mothers. There were great forests covering the temperate regions, where stands of giant sequoia shaded pine understories; there were spectacular sea cliffs, home to great clouds of mewling birds; there were crater jungle terraria of all kinds, and in the winters there were the endless plains of sastrugi snow; there were escarpments like vertical worlds, vast deserts of red shifting sands, volcano slopes of black rubble, there was every manner of biome, great and small; but for Sax this spare rock bioscape was the best.

He walked along over the rocks. His little car followed as best it could, crossing the tributaries of the Borealis upstream at the first car ford. The summertime flowering, though hard to pick out if one were more than ten meters away, was nevertheless intensely colorful, as spectacular in its way as any rain forest. The soil created by these plants in their generations was extremely thin, and would thicken only slowly. And augmenting it was difficult; all soil dropped in the canyons would wind up in the North Sea, and on the laminate terrain the winters were so harsh that soil availed little, it only became part of the permafrost. So they let the fellfields grow in their own slow course to tundra, and saved the soil for more promising regions in the south. Which was fine by Sax. It left for everyone to experience, for many centuries to come, the first areobiome, so spare and un-Terran.

Trudging over the rubble, alert for any plant life underfoot, Sax veered toward his car, which was now out of sight to his right. The sun was at much the same height it had been all day, and away from the deep narrow new Chasma Borealis running down the broad old one, it was very hard to keep oriented; north could have been anywhere across about one hundred and eighty degrees: basically, “behind him.” And it would not do to walk casually into the vicinity of the North Sea, somewhere ahead of him, because polar bears did very well on that littoral, killing seals and raiding rookeries.
