One reason why Horseshoe Lake should probably not be your next tour destination. (From what I can find, the Horseshoe Lake they are talking about in this video is by Mammoth Mountain in California.)

Digging a hole in the ground and sticking a lighter in there might not seem like the coolest science experiment, but it is interesting to see how quickly the flame goes out.

I am interested to see if National Geographic does any more recent updates on Yellowstone park and the surrounding areas. From what I have been able to find about that, ‘killer lake’ seems like too tame a term.
