I already answered this. To look for a trail to follow. That decision was made entirely with character knowledge and perceptions.
We don't know that it's trackless. I'm going in to find out. When I get in, my PC will have more knowledge and perceptions upon which to base further declarations.
How does your character know or even think to know that there might be trails that he cannot see and has no knowledge of? Why are you going to find out? Nothing you can see and no knowledge your character has can even lead to the question. The fact that you, the player, think there might be trails in there means that you are no longer in actor stance.
You are no different than the player who uses fire on the troll. You are acting on your genre knowledge and your understanding of the game. NOTHING about your decision is based on character knowledge or perceptions.
