Door to Hell

Does everybody remember the M.U.T.O. website, MUTOresearch.net ? This site had copious amounts of pictures and videos of the movie to bring in more people. Well, this picture was on it but the location wasn't featured in the movie (to the best of my knowledge, I saw it 3 times):

Now, here is information on the Door to Hell and M.U.T.O.'s involvement:

The image shows Turkmenistan's infamous burning 'Door to Hell', which was first ignited by a Soviet gas company in 1971. They claimed the dangerous gases would burn off in a few days -- yet miraculously, it has been burning ever since.  

Normally accessible to the public, the image is associated with the notes that this remote destination was strangely placed on government lockdown, as the secretive group identified as M.U.T.O. established a heavily-guarded "restricted access area" for undisclosed purposes. This snapshot from a tourist shows emergency vehicles, armed troops and research crews being choppered to the scene.  

After decades of this mysterious inferno blazing, why is M.U.T.O. getting involved now? -- TotalFilm

I have a feeling that this may actually be featured in a later movie, or maybe it was just scrapped. There's also the possibilty that I missed something in the movie.

Any thoughts? I'd love to hear outside opinions.
