 What is hiding underneath the gigantic mound on the alien planet?
The ice-cap, by its existence and circular shape, proved that the planet rotated at a not unreasonable rate. A water-ice ice-cap said that there were no poisonous gases in the planet's atmosphere. The fact was verified by the thick, dense cloud-masses which covered most of the surface,—all the surface, in fact, outside the ice-cap. Two of the Nadine's four-man crew watched out the same ports as the planet seemed to approach. All five of its proper company watched as the planet's surface enlarged. Now the space-yacht moved toward a vast mass of fleecy whiteness without any visible features. It was not until six thousand feet above the surface that the planet-wide cloud-level seemed to begin.
