"I should say not," Don agreed. "Millions of years."

She looked at him sharply. "I wasn't talking about the age of the Earth. I mean this room—this lookout post—whatever it is."

"Under the edge, you mean, with a downward view."

"That's right. From a distance I'd say Superior looked as if someone had cut the end off an orange. The flat part—where the cut was made—is the surface and we're looking out from a piece of the convex skin."
