Secret of the Martians

It is very funny about the ice cliffs. Up there it snows in the winter I guess because they get higher and higher until they are like mountains. Then in spring, they melt in a few days. Nobody knows much about the ice mountains because they are in the middle of the forbidden polar zone. It is said there are Martian people up in the forbidden circle but I don't think so. Because why would anybody live in such a place when the level lands and the old sea bottoms and the canals are down here!
