Rock Creek Caverns

Rock Creek Caverns is a location in Fallout 3. It is a large disconnected metro tunnel/cavern that is inhabited by mirelurks, mirelurk hunters, and/or mirelurk kings, depending on the player's level. The caverns consist of a single interior chamber.

Exterior
The entrance to Rock Creek Caverns is a sewer grate at the bottom of a crater that has exposed the sewer system, just to the north-northwest of the National Guard depot. When coming from the direction of the National Guard depot, there is a guaranteed encounter with two raiders and two super mutants. Some areas are moderately radioactive.
