I'm confused about the ice tunnels area where Ecks has awoken (square C19). Are all the buildings listed in that area buried in ice/connected by the tunnels? In other words, when Ecks first steps outside the storage shed, will she be above or beneath ground? I'm having trouble understanding where one enters and exits the ice tunnels; the hospital's description indicates that it can be entered from the rooftop but I was not sure if Ecks would be coming across it from above or below when she goes that direction.
