Gothic, Colorado is a busy former ghost town, hosting an annual summer camp for scientists and students in the Rocky Mountain Biological Laboratory. Scientists study the mysteries of the isolated and delicate alpine environment. They note changes in amphibian populations that may offer clues to global warming and long-term climate change. Many scientists believe that slight changes in amphibian's well-being may warn humans about subtle but serious environmental contamination.
