Farther inside the Ice Cave in Khatanga as we came closer to the Woolly Mammoth.

As you go farther into the ice cave where the woolly mammoth is stored the ice cave changes it's construction design.  Take a close look at this picture of the construction of the ice cave.  It is completely covered with ice, but it has a corrugated structure.  After I looked at this ceiling a little closer, it appeared to be made of metal sections very similar to what a Quonset Hut is built of.  It was impossible to verify this because our time inside the tunnel was limited.  

Just as we first entered the Russian man said that you can take as many pictures as you want, but you cannot use any video cameras.  On any expedition or tour that I've been on in my entire life, there is always someone who doesn't believe that the rules apply to them.  This was exactly the case here too.  Someone was using a video camera and the Russian man said that it was absolutely not allowed and we had to leave immediately.  He was not going to stand for people who cannot follow the rules and he made us leave at that very moment.  I really don't blame him, but with the sudden end of our examination, I didn't get to take as many photos as I wanted.
