“Or go into the cities and start a tour group, and a legal fund. Show people the land. Sue every change they propose.”

“Shit,” the young man said, shaking his head. “That sounds awful.”

“Yes it does,” Ann said. “There’s ugly work to be done. But we have to get them from the inside too. And that’s where they live.”

Long faces. They sat around and talked about it some more; the way they lived now, the way they wanted to live. What they might do to get from one to the other. The impossibility of the guerrilla life after the war was over. And so on. There were lots of big sighs, some tears, recriminations, encouragements.

“Come with me tomorrow and take a straight look at this ice sea,” Ann suggested.

The next day the guerrilla group traveled south with her along the sixtieth longitude, kilometer by difficult kilometer. Khala, the Arabs called it; the empty land. On the one hand it was beautiful, a Noachian desolation of rockscapes, and their hearts were full. On the other hand the ecoteurs were quiet, subdued, as if on a pilgrimage in some uncertain funereal mode. Together they came to the big canyon called Nilokeras Scopulus, and dropped into it on a broad rough natural ramp. To the east lay Chryse Planitia, covered by ice: another arm of the northern sea. They had not escaped it. Ahead to the south lay the Nilokeras Fossae, the terminal end of a canyon complex that began far to the south, in the enormous pit of Hebes Chasma. Hebes Chasma had no exit, but its subsidence was now understood to have been caused by the aquifer outbreak just to the west, at the top of Echus Chasma. A very great amount of water had gushed down Echus against the hard western side of Lunae Planum, carving the steep high cliff at Echus Overlook; then it had come to a break in that stupendous cliff, and had rushed down and through, tearing the big bend of Kasei Vallis, and cutting a deep channel out onto the lowlands of Chryse. It had been one of the biggest aquifer outbreaks in Martian history.

Now the northern sea had flowed back into Chryse, and water was filling back into the lower end of Nilokeras and Kasei. The flat-topped hill that was Sharanov Crater stood like a giant castle keep on the high promontory over the mouth of this new fjord. Out in the middle of the fjord lay a long narrow island, one of the lemniscate islands of the ancient flood, now islanded again, stubbornly red in the sea of white ice. Eventually this fjord would make an even better harbor than Botany Bay: it was steep-walled, but there were benches tucked here and there that could become harbor towns. There would of course be the west wind funneling down Kasei to worry about, katabatic onslaughts holding the sailing ships out in the Chryse Gulf. . . .
