i just bumped into this article, and it really amazed me. it is just so wonderful that there is in fact as big as this. I thought i can only see the largest crystals from clark kent's humble abode on the tv series smallville. http://news.nationalgeographic.com/news/2007/04/photogalleries/giant-crystals-cave/index.html
