It was change on a massive scale, becoming apparent everywhere now, and accelerating every year as the summers got warmer, and the submartian biota grew deeper— while everything still froze solid every winter, and froze a little bit almost every summer night. Such an intense freeze-thaw cycle would tear any landscape apart, and the Martian landscape was particularly susceptible to it, having been stalled in a cold arid stasis for millions of years. Mass wasting was causing many landslides a day, and fatalities and unexplained disappearances were not at all uncommon. Cross-country travel was dangerous. Canyons and fresh craters were no longer safe places to locate a town, or even to spend a night.

Sax stood and walked to the window of his room, looked down at the lights of the city. All of this was as Ann had predicted to him, long ago. No doubt she was noting reports of all the changes with disgust, she and all the rest of the Reds. For them every collapse was a sign that things were going wrong rather than right. In the past Sax would have shrugged them off; mass wasting exposed frozen soil to the sun, warming it and revealing potential nitrate sources and the like. Now, with the conference fresh in his mind, he was not so sure.

On the vid no one seemed to be worrying about it. There were no Reds on vid. The collapse of landforms were considered no more than an opportunity, not only for terraforming, which seemed to be considered the exclusive business of the transnats, but for mining. Sax watched a news account of a freshly revealed vein of gold ore with a sinking feeling. It was strange how many people seemed to feel the lure of prospecting. That was Mars as the twenty-second century began; with the elevator returned they were back to the old gold rush mentality, it seemed, as if it really were a manifest destiny, out on the frontier with great tools wielded left and right: cosmic engineers, mining and building. And the terraforming that had been his work, the sole focus of his life, in fact, for sixty years and more, seemed to be turning into something else. . . .
