" The lake was so full of holes and mounds that it reminded Stanley of pictures he’d seen of the moon"
The moon’s surface
is marked with craters from the impact of asteroids as well as ancient volcanic eruptions. There are also mounds, domes and wrinkles formed by ancient volcanoes and lava. Pictures of the moon show a surface that looks pockmarked and rough. Parts of the surface appear very dark due to the iron in the basalt plains formed by cooling lava; the lighter areas are the ancient “highlands”. This is what makes the moon appear ‘patchy’ from a distance.
