I have turned on tree lights of knowledge (pink, green, yellow and all those pedestals are raised). 
 
 I gave the watch to the boy, so I could get the white gem. BUT I CANT FIND THE WAY TO THE LAST PYRAMID!! 
 
 I suppose that's where I should place the last gem
  
 
  
  
    You found the firewood right? Just look around in that area, that's your way in.
  
 
  
  
    I'm stuck here too! I have the firewood but can't seem to go any further in that area. I can't drop down to the big room with the mine car tracks because the fall kills Indy.
  
 
  
  
    you dont need to drop down there..only need to jump across..
