After you escape Raven Rock you can ask him after he kills the remaining Enclave outside. You can only have Fawkes as a follower if your karma level is Good or higher. This is where the problem starts, most people would kill random people gaining negative karma so you cant have him at this point.
During the time you speak to him he says that he will be researching American History. After this you can fast travel to 'The Museum of History'. One problem he may still be taking a peace walk killing random raiders. So once you arrive and hes not there, wait 24 hours and do a full 360 degree turn (this may sound stupid but its quicker that exiting the whole place) if not there try again.
Eventually it will work... and you will have your Super Mutant follower with a Gatling Laser :D
No, after its been destroyed or not been destroyed you cannot re-enter Raven Rock

You can find President Eden in Fallout 3 at Raven Rock, but he is also a computer!
In the top left corner of the map there is a place called Raven Rock, they are there.
All of your followers will return to where you recruited them from (except for Fawkes & RL-3; RL-3 will go to Canterbury Commons and Fawkes will be outside Raven Rock when you exit).
no it is covered in rubble, but it is still on your pip boy map
Raven Rock State Park was created in 1969.
Raven Rock State Park is located at 3009 Raven Rock Road in Lillington, North Carolina. It is about a 45 minute drive from Fayetteville.
There is a hollowed out rock near megaton.
you can only get into raven rock during the quest where you go to get the geck and when you start to leave you are taken there. Once you leave raven rock after this you cannot go back in it.
It is right next to the Broadcast Tower KB5 and near the Dickerson Tabernacle Chapel. If you head NW from paradise falls you will come to it. It is also SE of Raven Rock. It is also in the same vicinity of Mount Mabel Campground (Deathclaw Sanc is North of it.)
if you mean raven rock once you leave you cannot get back in as the door is closed
