>>The only thing I could think of is that I think the Marauder's Map 
is limited to the Hogwarts grounds and castle, which possibly 
excludes the Forest and the Shack.
The Shack is in Hogsmeade, even though it is close, it would not 
be on the map.<<
 
dorapye agreed:
>Yeah, this is my way of making sense of it too. When we are first 
introduced to the map, it is described as showing the "Hogwarts 
castle and grounds" . Fred and George then go onto explain to Harry 
where the passage from behind the one-eyed old crone leads...I take 
this to mean it cannot be deduced from the map because Hogsmeade is 
not shown on the map...<

KathyK, being a very bad girl and not finishing her packing says:

You three are all correct.  Your way of making sense of it is 
actually stated right in canon.  Snape says to Lupin (PoA "The 
Servant of Lord Voldemort," US ed., pg 358) "I saw you running along 
this passageway and out of sight."  From this, we can deduce two 
things.  The first is that the Shrieking Shack, located in 
Hogsmeade, is not plotted on the Marauder's Map.   

The second thing we can understand from Snape's statement is Snape 
*knew* no one was in the Shrieking Shack except for Lupin because 
none of the others in the Shack appeared on the Map.  Snape strongly 
suspected Sirius would be there.  He's suspected Lupin all year of 
helping Sirius and jumped at the chance to confirm his suspicions.  
Why else would Lupin be going there?  He doesn't need to hide out in 
there now that he's got the Wolfsbane Potion.  Was he attacked with 
a sudden rush of nostalgia so he decided to run off without taking 
his potion?  Absolutely not.  Snape knows this.  Snape is certain 
Sirius is there.

As for the second part of the discussion, which I so kindly snipped 
out of there, I'm going to refer you to one of bboy_mn's posts.  
He's got a very logical and very convincing theory as to why Lupin 
missed the second Harry and Hermione on the Map without making Lupin 
ESE (although I *love* that theory).  Since I'm not actually 
supposed to be spending my time here at the moment, I'll just give 
you this first link I found.
