Cliffside Cavern

Cliffside Cavern is a raider outpost in the southern portion of the Capital Wasteland (east of Tenpenny Tower). It requires 75 lockpick to enter, but if you approach the cave by traveling northeast from The Overlook Drive-in(Xbox360). Inside, there is a Chinese Army: Special Ops Training Manual on one of the shelves. There is also a copy of Grognak the Barbarian in the main cavern at the base of the generator on the top walkway, closest to the east exit to the wasteland. There are three exits from the cavern; two lead to the wasteland, while the other leads deeper into the caves to an area called Yao Guai Cave that has no other exits. As the name suggests, it is full of Yao Guai.

 * Nuka Cola Quantum in near generators near entrance of cavern.
 * Mini-Nuke on top of safe in Raider tent (first cavern)
 * Nuka Grenade Schematics at the back of the Yao Guai Cave, lower level near skeletons.
