Slowly her view zoomed in. They got lined up on the runway, which was still too distant to be clearly visible. Beyond the airport was the city itself, only a few buildings and towers raising their heads above what looked to be a well-tended canopy of shade trees. It had a lot of parks. The city’s outskirts faded to a grayer shade—newer developments, perhaps, with less mature trees? Just to the right of their projected course was a big lake, buffered from the open greensward of the airport by a nubby carpet of vegetation so dark green it was almost black. She could tell from the lake’s shape that it was artificial. Dutchwoman that she was, she couldn’t help tracing its shoreline until she identified the long straight section that had to be the dam. It was a low earthen structure pierced by a spillway, not far beyond the end of the runway.
