There are three methods for reckoning the eastern and western extremes of the United States.
One method is to use the
Prime Meridian as the dividing line between east and west. This meridian running through Greenwich, London, is defined as zero degrees longitude and could be called the least eastern and least western place in the world. The 180th meridian, on the opposite side of the globe, is therefore the easternmost and westernmost place in the world.
Another method is to use the
International Date Line as the easternmost–westernmost extreme. On the equinox, the easternmost place would be where the day first begins, and the westernmost is where the day last ends.
Still another method is to first determine the
geographic center of the country and from there measure the shortest distance to every other point. All U.S. territory is spread across less than 180° of longitude, so from any spot in the U.S. it is more direct to reach the easternmost point, Point Udall, U.S. Virgin Islands, by traveling east than by traveling west. Likewise, there is not a single point in U.S. territory from which heading east is a shorter route to the westernmost point, Point Udall, Guam, than heading west would be, even accounting for circumpolar routes. The two different Point Udalls are named for two brothers from the Udall family of Arizona; Mo Udall (Guam) and Stewart Udall (Virgin Islands), sons of Chief Justice Levi Stewart Udall of the Arizona Supreme Court, both served as U.S. Congressman.

The Aleutian Islands (; Russian: Алеутские острова; Aleut: Tanam Unangaa, literally "Land of the Aleuts", possibly from Chukchi aliat, "island"), also called the Aleut Islands or Aleutic Islands and known before 1867 as the Catherine Archipelago, are a chain of 14 large volcanic islands and 55 smaller ones belonging to both the U.S. state of Alaska and the Russian federal subject of Kamchatka Krai. They form part of the Aleutian Arc in the Northern Pacific Ocean, occupying an area of 6,821 sq mi (17,666 km2) and extending about 1,200 mi (1,900 km) westward from the Alaska Peninsula toward the Kamchatka Peninsula in Russia, and mark a dividing line between the Bering Sea to the north and the Pacific Ocean to the south. Crossing longitude 180°, at which point east and west longitude end, the archipelago contains both the westernmost part of the United States by longitude (Amatignak Island) and the easternmost by longitude (Semisopochnoi Island). The westernmost U.S. island in real terms, however, is Attu Island, west of which runs the International Date Line. While nearly all the archipelago is part of Alaska and is usually considered as being in the "Alaskan Bush", at the extreme western end, the small, geologically related Commander Islands belong to Russia.
The islands, with their 57 volcanoes, form the northernmost part of the Pacific Ring of Fire. Physiographically, they are a distinct section of the larger Pacific Border province, which in turn is part of the larger Pacific Mountain System physiographic division.
These Islands are most known for the battles and skirmishes that occurred there during the Aleutian Islands Campaign of World War II. Attu and Kiska were the only two foreign invasions of the United States during that war.

Geography of the United States
The term "United States", when used in the geographical sense,
is the contiguous United States, the state of Alaska, the island state of Hawaii, the five insular territories of Puerto Rico, Northern Mariana Islands, U.S. Virgin Islands, Guam, and American Samoa, and minor outlying possessions. The United States shares land borders with Canada and Mexico and maritime borders with Russia, Cuba, and the Bahamas in addition to Canada and Mexico. The northern border of the United States with Canada is the world's longest bi-national land border.
List of geographic centers of the United States
This is a list of geographic centers of each U.S. state.

The geographic center of North America lies near Rugby, North Dakota 48°22′2″N 99°59′46″W, though this designation has no official status.
Naalehu is a community in Hawaii County, Hawaii, United States. Naʻālehu means "the volcanic ashes" in Hawaiian. It is the southernmost community with a post office in the 50 states of the United States. (See List of extreme points of the United States.) For statistical purposes, the United States Census Bureau has defined Naalehu as a census-designated place (CDP). The census definition of the area may not precisely correspond to local understanding of the area with the same name. The population was 866 at the 2010 census, down from 919 at the 2000 census.
Peaked Island (Alaska)
Peaked Island is an uninhabited island located in the Aleutian Islands chain in Alaska. It is the westernmost point in the 50 states by direction of travel, and last sunset (at equinox) in U.S. territory. West of it passes the International Date Line, after which come Russian territorial islands.
