Her co-op was based in Moreux Crater, in the Protonilus Mensae, between Mangala and Bradbury Point. It was a big crater, puncturing the long slope of the Great Escarpment as it fell down toward the Boone’s Neck peninsula. The co-op was always developing new varieties of molecular netting to replace earlier nets, and the old tent fabrics; the mesh they had installed over Moreux was the latest thing, the polyhydroxybutyrate plastic of its fibers harvested from soybean plants, engineered to produce the PHB in the plants’ chloroplasts. The mesh held in the equivalent of a daily inversion layer, which made the air inside the crater about thirty percent thicker and considerably warmer than the outside air. Nets like this one made it easier to get biomes through the tough transition from tent to open air, and when permanently installed, they created nice meso-climates at higher altitudes or latitudes. Moreux extended up to forty-three degrees north, and winters outside the crater were always going to be fairly severe. With the mesh in place they were able to sustain a warm high-altitude forest, sporting an exotic array of plants engineered from the East African volcanoes, New Guinea, and the Himalayas. Down on the crater floor in the summer the days were seriously hot, and the weird blooming spiky trees as fragrant as perfume.

The crater’s inhabitants lived in spacious apartments dug into the northern arc of the rim, in four set-back levels of balconies and broad window walls, overlooking the green fronds of the Kilimanjaro slope forest underneath them. The balconies baked in the sun in the winter, and rested under vine-covered trellises in the summer, when daytime temperatures soared to 305 K, and people muttered about changing to a coarser mesh to allow more hot air to escape, or even working up a system where they could simply roll off the mesh during the summer.
