There aren’t even any insects buzzing about. The Berkeley Pit had become one of the deadliest places on earth, too toxic even for microorganisms. Or so it was thought.

He snagged a sample and brought it to biologist Grant Mitman at the nearby Montana Tech campus of the University of Montana, where Mitman found to his amazement that the goop was a mass of single-celled algae. This makes it a classic example of an extremophile.
Extremophiles are organisms that can tolerate and even thrive in environments that will destroy most other living things. Some can even repair their own damaged DNA, a trait which makes them extremely interesting to cancer researchers.
