East Coast

The East Coast, also known as the "Eastern Seaboard" or "Atlantic Seaboard," refers to the easternmost states of the pre-War United States. While in a strict geographical sense it includes the entire eastern seaboard, in popular usage the term "East Coast" is most often used to specifically refer to the northern half of this region, which is also known as the Northeastern U.S.

Adams Air Force Base
Adams Air Force Base was once a major military installation of the United States in pre-War times. Located just outside the Capital Wasteland, the base is accessible through the Presidential Metro, and in 2277 served as a secondary headquarters for the Enclave, besides their original facility at Raven Rock. Enclave operations were centered in the Mobile Base Crawler, which had the capability to call down orbital strikes on several locations in the Capital Wasteland.

Broken Banks
Broken Banks was a region on the route traveled by the ferry Duchess Gambit, which also stopped at the Commonwealth and the Capital Wasteland. Nothing is known about it except that it is south of the Capital Wasteland and may refer to a location in the Carolinas.

Capital Wasteland
The Capital Wasteland is a large expanse of open areas with caves, raider camps, etc. in the area of the former Washington, DC around the more urban areas of Downtown DC. As of 2277, the area is overrun by super mutants who are in a constant battle to push humans out.

The central hub of civilization in the ruins of the former capital is Rivet City, based in and around the remains of a beached aircraft carrier. Other settlements include the towns of Megaton, Canterbury Commons, Andale, Tenpenny Towers and Paradise Falls, as well as the Brotherhood of Steel Citadel built in place of the pre-War Pentagon. Movement between the certain areas is possible through the Washington Metro tunnels.

Commonwealth
The Commonwealth is what is left of the pre-War state of Massachusetts. While it too was ravaged by the Great War and is as lawless and inhospitable as much of the former United States, its main attraction is the mysterious Institute. The Institute itself has developed highly advanced technology and even artificial intelligence, which it has used to create a population of subservient androids. An opposing organization in the Commonwealth, the Railroad, works to eventually free the enslaved androids from their creators.

Crater Banks
Nothing is known about this area, other than the fact that it is on the coast. This is due to the fact that it was only mentioned once, in a single line of dialogue from Quinn in the Underworld. The line in which it's mentioned is "Oh, here and there and everywhere. I've explored all up and down the coast, from the Commonwealth, to the Pitt, all the way down to Crater Banks," which he says in response to the player asking "Travel? Where do you go?".

Great Lanta
Great Lanta is the birthplace of Saint Monica, who is venerated by the Church of Saint Monica aboard Rivet City in the Capital Wasteland. The exact location of Great Lanta is unknown, Father Clifford says in his sermon that Great Lanta is "on the shores of the ocean,".

Point Lookout
The region of Point Lookout, Maryland, just south of the Capital Wasteland, was home to a small seaside resort town established after the 1950s. Point Lookout was one of the few places in the United States not directly hit by nuclear bombs during the Great War, but since then the site has become a massive coastal swamp.

Erie Stretch
The Erie Stretch is a vague region located somewhere along the Lake Erie coast, possibly the area of Erie, Pennsylvania. Even less is known about the Erie Stretch than Ronto, except that it was known to the inhabitants of The Pitt in 2277.

The Pitt
The Pitt is a raider settlement built from the decaying infrastructure of the city of Pittsburgh, Pennsylvania. The settlement is divided into two main areas: Downtown, where slaves work and live, and Uptown, where the raiders live. Downtown includes quarters for the slave population, The Mill, and the abandoned Steelyard which is inhabited by Wildmen and trogs. Uptown features the Abandoned Apartments and Haven building, the personal palace for The Pitt's leader, Ishmael Ashur. A network of ramps and bridges connects the upper floors of The Pitt's dilapidated buildings in both parts of the settlement, serving as platforms for raiders to oversee the working slaves.

Ronto
Little is known about Ronto, the true location of Ronto is unknown. By 2277 Ronto had established itself as a notable power in the area with a reputation that reached as far as The Pitt.
