Rockopolis

Rockopolis was once a hidden, underground settlement, but is now a small abandoned cave with a single interior section. It is located at the western edge of the Capital Wasteland, north of Girdershade and southeast of the Yao Guai Tunnels. A good tip to find Rockopolis is to fast travel to Smith Casey's Garage, and walk directly west until you see pennants over a boulder.

Background
According to files on Herbert Dashwood's computer and the accounts of The Adventures of Herbert "Daring" Dashwood on Galaxy News Radio, Rockopolis was once a hidden underground village. The inhabitants would only allow outsiders in if they presented a secret knock. The leader of Rockopolis at the time was King Crag. Herbert accidentally led Penelope Chase, a slaver leader, to Rockopolis. According to Herbert Dashwood's computer, the incident led to the enslavement of the city's population and the destruction of the city itself. The fact that the population was enslaved is confirmed by the Rollings -- We're Done note found there. Part of Rockopolis is blocked off by a pile of rocks, however there is nothing behind the rocks and it is easy to get stuck.

Exterior
The entrance is a boulder that can be interacted with like any other door or entrance. Facing the boulder, there is one dead tree on the right, two on the left. And as the attached pictures show, there is a length of bunting above the boulder. It is easiest to find at night, as there are lights glowing on the rock face as you approach it from the East. The entrance is very close to the center of that particular square on the map. A random encounter location is near the entrance. There is a string of multicolored pennants (much like those found in Little Lamplight) above the entrance boulder.

If you approach from above, you'll see a small canyon - keep looking down - you'll notice a soft glow. Jump down and you'll have the option of entering Rockopolis without ever seeing the exterior.

Interior
The only accessible section of Rockopolis is a small area with some random objects. The tunnel to what was the rest of Rockopolis itself is permanently blocked by rocks. The area has the appearance of a cave dwelling, but lacks any beds. The corpse of Argyle can be found here.

 * It is possible to become stuck in a small pit if the player climbs the rocks to the left of Argyle's body. To escape on PC turn off collision in the console with the TCL command. To escape on Xbox 360 and PS3 versions, head to the end of the pit behind the rocks and jump up them till you're on top, head back left (jumping if necessary) until you're clear of potential obstructions then simply walk back down.
 * Upon entering Argyle's body may not appear.
