I'm making a player map for my D&D campaign (we are about to enter Thunderspire Labyrinth). I want the map to be mysterious yet helpful. This is the current version of the map, which I sneakily did this morning at work.

Questions: is it clear enough? I intentionally left out scale and north, not sure why really. Are the symbols relatively obvious? They are supposed to indicate: mine!; reservoir!; dwarves!, and underdark! (its ok that the latter is a bit obscure). Is it obvious that the map displays passages cut into rock, and that the paler areas are better known? Thanks for any advice.
