![]() In his 1959 paper on the search for the center of America, Adams wrote that the very idea of the country having a center "is a conception that depends almost entirely for its existence upon the curiosity of mankind." In looking for that middle point, Adams saw how arbitrary and illusory the idea was, having moved the point himself not once but twice. If you think Adams’ search was a silly one, you’re not alone. Ever since 1959, the title of America’s center has belonged to a humble cattle pasture in Belle Fourche, South Dakota. Lo and behold, Kansas finally lost the center of the States. So he stuck the new states next to Washington, Nosowitz writes. Now Adams had a real dilemma: if he counted the distance between the new states and the continental U.S., that would place the country’s center smack in the middle of the Pacific Ocean. But the real trouble came a few years later, when Hawaii and Alaska joined the Union. Only now it was about 40 miles north of Meades Ranch on an old hog farm in the town of Lebanon. Wherever it balances, that’s the center.”Īccording to the center-of-gravity method, America’s center was still in Kansas. Now balance that cardboard map on one point. “Basically: imagine the entire country is laid out on a piece of cardboard, cut precisely around its borders so you have a perfect, evenly thick map of the United States. They took a map of the United States and cut out the borders on a sheet of cardboard and used what Adams called the “center-of-gravity method,” writes Nosowitz: So, Adams and his team came up with a new idea. New Mexico and Arizona officially became states in 1912, changing America’s borders. You see, there was one big problem with trying to find the center of America in the early 20th century: the country kept growing. Coast and Geodetic Survey simply picked a spot that looked good, a place in Kansas called “Meades Ranch.” A bronze marker was placed on the spot, and surveyors used that marker from 1927 all the way up until 1983, though over those years the “official” center moved twice. Adams writes that the first center was chosen rather haphazardly: the U.S. Adams, a mathematician with the NOAA’s United States Coast and Geodetic Survey. The government’s search for the center of America is best chronicled in a 1959 report by Oscar S. But even so, mathematicians and mapmakers spent years trying to answer the question. It’s also an incredibly difficult mathematical problem to solve, writes Dan Nosowitz for Atlas Obscura, because the United States is an irregular shape wrapped around an enormous sphere. There’s no real reason for figuring out the middle of the country, aside from giving cartographers a point of reference and perhaps creating a tourist trap. ![]() Finding the center of the United States is an odd and old pursuit - one that the National Oceanic and Atmospheric Organization has taken a stab at several times over the years.
