This photo was taken during a trip to Baikal Lake, in Russia. The first morning we where there, aour guide, Julia, found a little cave, and when She told us about it I didn't have any doubt and decided to enter into it. I asked one of my collegues, César, to stand for a while just to take the photo, and this was the result of it.
The name of the photo is due to the bat shape that the ice makes in the entrance of the cave. It reminds me to the Batman movies :-)
