Hot as Hell: Firefighting foam heats up coal fire debate in Centralia, Pa.

By some accounts, Hell on Earth is located directly below Centralia, Pa.: Smoke rises from the cracked ground, smoldering sinkholes open without warning, and what is left of the town’s abandoned houses and surrounding woodlands is scorched and covered in a layer of smelly sulfur.
