There are a number of different interpretations for "easternmost" and "westernmost"; see
for full treatment.
This is a list of the
extreme points of the , the points that are farther north, south, east, or west than any other location in the country. Also included are extreme points in elevation, extreme distances, and other points of peculiar geographic interest. United States
Extreme points in the 50 states: Point Barrow, Ka Lae, Sail Rock, Peaked Island
Extreme points in the contiguous 48 states: Northwest Angle, Ballast Key, Sail Rock, Bodelteh Islands
Extreme points of the U.S. on the North American continent: Point Barrow, Cape Sable, West Quoddy Head, Cape Prince of Wales
Northernmost points [edit ] Point Barrow, Alaska – northernmost point in all 71°23′20″N 156°28′45″W / 71.38889°N 156.47917°W U.S. territory Barrow, Alaska – northernmost incorporated place in all U.S. territory, population about 4,000 71°17′44″N 156°45′59″W / 71.29556°N 156.76639°W Fairbanks, Alaska – northernmost city of more than 20,000 residents, and northernmost city with public road access 64°50′22.94″N 147°43′14.63″W / 64.8397056°N 147.7207306°W Anchorage, Alaska – northernmost city of more than 250,000 residents 61°13′4.17″N 149°53′33.17″W / 61.2178250°N 149.8925472°W Northwest Angle Inlet in Lake of the Woods, Minnesota – northernmost point in the 48 49°23′04.1″N 95°9′12.2″W / 49.384472°N 95.153389°W contiguous states (because of incomplete information at the time of the Treaty of Paris (1783) settling the American Revolutionary War) Sumas, Washington – northernmost incorporated place in the 48 contiguous states (because of 19th century survey inaccuracy placing the international border slightly north of the 49°00′08.6″N 122°15′40″W / 49.002389°N 122.26111°W 49th parallel here. ) [1 ] Bellingham, Washington – northernmost city of more than 50,000 residents in the 48 contiguous states 48°45′19.12″N 122°28′43.54″W / 48.7553111°N 122.4787611°W Seattle, Washington – northernmost city of more than 500,000 residents in the United States 47°36′13.81″N 122°19′48.56″W / 47.6038361°N 122.3301556°W Alaska has the northernmost geographic center of all the states. North Dakota has the northernmost geographic center of the 48 contiguous states. Note that maps of the 48 states that are displayed in a non-cylindrical projection (i.e. curved lines of latitude) can give the impression that the state of Maine extends farther north than it actually does. The northernmost point in Maine is at approximately 47.46 degrees North latitude. This line of latitude passes through the southern suburbs of Seattle. From there, it is approximately 100 miles (160 km) north to the 49th parallel. A wide swath of land within the 48 states (encompassing portions of Washington, Idaho, Montana, North Dakota, and Minnesota) is therefore farther north than any place in Maine. Included in this area are such places as Spokane, Washington; Coeur d'Alene, Idaho; Great Falls, Montana; Minot and Grand Forks, North Dakota; and Bemidji, Minnesota. Even Isle Royale and parts of the Upper Peninsula of Michigan (such as the Keweenaw Peninsula) are farther north than anywhere in Maine. By comparison, the southernmost land in Canada, Middle Island, Ontario,at a latitude of North 41°40'53", lies entirely south of 12 of the contiguous states - Washington, Idaho, Minnesota, Montana, North Dakota, Michigan, Maine, Wisconsin, Oregon, South Dakota, New Hampshire and Vermont - and south of the northernmost border of 14 more of the contiguous states.

Florida has the southernmost geographic center of the 48 contiguous states. Note that maps of the 48 states that are displayed in an equal-area projection can give the impression that the state of Texas extends farther south than it actually does. The southernmost point in Texas (just southeast of Brownsville) is at approximately 25.84 degrees North latitude. This line of latitude passes through Hialeah, Florida, which is slightly north of Miami.

Note that maps of the 48 states that are displayed in an equal-area projection can give the impression that the state of Florida extends farther east than it actually does. The easternmost point in Florida (Palm Beach Shores) is at approximately 80.03 degrees West longitude. This line of longitude passes through (or near) such places as Charleston, South Carolina; High Point, North Carolina; Salem, Virginia; Morgantown, West Virginia; and Pittsburgh and Erie, Pennsylvania – farther west than all of New York, New Jersey, and all of the New England states.

Oregon has the westernmost geographic center of the 48 contiguous states. Note that maps of the 48 states that are displayed in an equal-area projection can give the impression that the state of California extends farther west than it actually does. The westernmost point in California (Cape Mendocino) is approximately seven miles east of the westernmost point in Oregon (Cape Blanco), and approximately 14 miles (23 km) east of the westernmost point in Washington (Cape Alava). Interpretation of easternmost and westernmost [edit ]
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 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 Point Udall, Guam, than heading west would be, even accounting for circumpolar routes. The two Udalls for whom the two Points are named were brothers,
Mo Udall in Guam and Stewart Udall in the Virgin Islands.

If Puerto Rico became the 51st state, the easternmost point of the 51 states would be Culebrita (by direction of travel), and the southernmost point in all of the states would be Caja de Muertos. Hawaii and Maine would each lose their title of southernmost/easternmost points respectively, though Maine would still have the easternmost point on the mainland.
