Okefenokee Swamp
Okefenokee Swamp is located in the state of Georgia. Peat has been accumulated for thousands of years and absorbed into itself any buildings and roads that people have built. And also, Okefenokee Swamp is teeming with carnivorous plants, large swarms of mosquitoes and insects, frogs, poisonous snakes, and thousands of alligators that are dangerous to humans.
