Musty caverns

The musty caverns is an unmarked location in the Capital Wasteland, located east of Mason Dixon Salvage.

Exterior
It appears as a regular ant hill entrance.

Interior
The interior layout is almost identical to the Ant mound in Fallout: New Vegas. It features several long, narrow tunnels that are dotted with cave fungi, among other things. At the end of the tunnels, there is one round room with two corpses that have little to no valuable loot on them.

Inhabitants
Outside of the cave is a respawn point for enemies, mainly varieties of giant ant and radscorpion as well as deathclaws at higher levels. Immediately inside the cavern there are also giant soldier ants.

Appearances
The musty caverns appear only in Fallout 3.
