Maze Under the Ice

Jacob's words drew Charlotte and Geko's attention as they looked at the 6-meter-in-diameter hole left behind by the snow monster. 

Geko frowningly asked, "Why do you think it's their lair and not a trap?" 

Jacob coolly said as he approached the dark hole, "This will explain how they were able to come and go as they pleased, and we didn't find any inhabitant in this place. So, now it becomes quite clear that we were looking in the wrong direction all along. 

"They won't live on the surface but underground. Think about it: this entire place is covered with solid ice, and we have no idea just how deep it is or if there's any ground under it or a body of water. 

"But one thing is clear: those fur balls are capable of traveling anywhere in these blasted ice lands, and they always know where we are. This will also explain this, and they can always cover their tracks with snow around us quite easily.
