Maya went out with Diana to look at one of these pipes in action. Seen from a dirigible floating overhead, they looked remarkably like a garden hose lying on the ground, snaking back and forth under the high pressure of the spurting water.

Down on the ground it was more impressive, even bizarre; the pipeline was huge, and it rolled majestically over layers of smooth ice already deposited, held a couple of meters over the ice on squat pylons that ended in big pontoon skis. The pipeline moved at several kilometers an hour, pushed by the pressure of the water spewing out of its nozzle, which pointed at various angles set by computer. When the pipeline had skiied out to the end of its arc, motors would turn the nozzle, and the pipeline would slow down, stop, and reverse direction.

The water shot out of the nozzle in a thick white stream, arcing out and splashing onto the surface in a spray of red dust and white frost steam. Then the water flowed over the ground, in great muddy lobate spills, slowing down, pooling, settling flat, then whitening, and shifting slowly to ice. This was not pure ice, however; nutrients and several strains of ice bacteria had been added to the water from big bioreservoirs located back at the beachline, and so the new ice had a milky pink cast, and melted quicker than pure ice. Extensive melt ponds, actually shallow lakes many square kilometers in area, were a daily event in the summer, and on sunny spring and fall days. The hydrologists also reported big melt pods under the surface. And as worldwide temperatures continued to rise, and the ice deposits in the basin got thicker, the bottom layers were apparently melting under the pressure. So great plates of ice over these melt zones would slip down even the slightest of slopes, piling up in great broken heaps over all the lowest points on the basin floor, in areas that were fantastic wastelands of pressure ridges, seracs, melt pools that froze every night, and blocks of ice like fallen skyscrapers. These great unstable ice piles shifted and broke as they melted in the day’s heat, with explosive booms like thunder, heard in Odessa and every other rim town. Then the piles froze again every night, booming and cracking, until many places on the basin floor were an inconceivably shattered chaos.
