Archaeology has to contend with plenty of enemies—forces that attack and destroy artifacts.
Most are microscopic, like bacteria or rust, and some are invisible, like wind and earthquakes. Of course, humans are always an issue; looters and vandals have been ruining sites since at least the time of ancient Egypt.
Luckily, planet Earth has a few “safe houses”—places where artifacts have lasted for thousands of years. Bacteria don’t move in because it’s too hot, too cold, or too dry. The objects are sheltered from wind and waves. Earthquakes, volcanoes, and hurricanes can’t get at them—and neither can destructive humans.
Where are these safe havens?
