Area 51 is in the northern part of nevada, north of Las vegas by 120 miles and 20 miles away from Rachel. Area 51 is seven miles away from the edge of restricted air space at it's closest point. To its south is the less famous Area S4. S4 is about 40 miles at its closest point and thatmakes it hard for the public to view the base. It has been speculated that Area 51 is there just to draw attention away from Area S4 which is supposedly where UFO's are kept. Description of the base Area 51 has nine large hangars. These hangers are probably where the Black Book Projects are located. Area S4 is built into the mountain with the hangar doors built at the same angle as the mountain for additional camouflage. These doors are covered with sand-colored paint to blend in with the land around it. Bob Lazar said there are guards with dogs all around and inside the base. Inside S4 is a security guard and a scanner that reads your whole hand. The Area can't be accuratly describe because the sources of information are limited at best. There is even less known about Area S4. All that is known has come from one source, and that's Bob Lazar. He supposedly worked there and has since quit.
