Marauders Map and Unplottable Chambers

I'm sure it's been asked before, but what would Fred and George have 
found if they had used the Marauder's Map to look in the 3rd Floor 
Corridor in Book 1 or searched for the Chamber of Secrets in Book 2?

I think everyone would agree that in Book 1 F&G would have looked in 
the 3rd Floor Corridor with the map as soon as they had been told the 
Corridor was out of bounds. In Book 2 they would have looked for the 
Chamber after Halloween when everyone and their sistrer was checking 
out Hagwart's: A History.



Obvious Answer: We read in book 4 (and in FB) about unplottable 
charms. There is most likely something of this type over the entirety 
of Hagwart's, Diagon Alley, Durmstrang, and Beauxbaton. Is it 
possible to place a localized unplottable charm  on one corridor or 
chamber?

I suggest it would be possible but extremely difficult. The Chamber 
of Secret would have had one, built into it from the beginning by 
Slytherin and probably cast over several years with dark magic 
sustaining it (and possibly keeping the basilisk vital)

However the third floor corridor and maze was most likely set up over 
weeks or months. Dumbledore placed the Mirror of Erided in it only 
after Xmas. And IF it were possible or feasible to put an unplottable 
charm around one chamber, wouldn't the Marauder's Map have been full 
of unreadable areas from overprotective wizards? Could you have seen 
Snape or Moody not shielding ther quarters? (More later)

Point of Observation: I bevieve that to Fred and George, thge Map was 
a Toy, a toll to sneak around, but not the prized possession that it 
was for Harry. 

Also Fred and Georger although jokesters and rule benders did not 
possess the capacity of curiosity and recklessness of HRH. When they 
looked at the third floor corridor and saw a Hellhound stalking the 
hall, they most likely gave up looking further. If they had they 
would have found empty chambers (would the charms or stone even be 
noted on the map?) Remember the original writers were exploreres and 
rulebreakers, but not thieves.

I don't think either F or G had the patience to  sit for hours 
wataching the map for a thorough search of the school's chambers. Or 
else we come to the final mindbender.

What would F & G have seen in SorSt if they had looked in Querrill's 
room? Would the map have named Voldemort?
