I  ·  The Center

A point on the prairie.

About twenty miles north of Belle Fourche, South Dakota, in a cattle pasture in Butte County, lies the geographic center of the United States — all fifty states, from Maine to Hawaii and Alaska.

Its coordinates are 44°58′ north, 103°46′ west. Written without the symbols, they become the name of this site: 4458N 10346W.

There is no town at the center, no gift shop, and most days nobody at all. There is a survey marker, a flag, and grass and sky in every direction. The pages that follow explain what the numbers mean, how a quiet pasture came to be the middle of America, and how to go and stand there.

II  ·  The Numbers

Reading 4458N 10346W.

Every place on Earth can be named by two angles: how far north or south of the equator it lies, and how far east or west of the Prime Meridian at Greenwich, England. Each degree is divided into sixty minutes.

A "geographic center" is the point on which a flat map of the country would balance if it were cut from a sheet of uniform thickness. The National Geodetic Survey notes that there is no single agreed definition, and the result depends on how the shape is drawn. The figure here is the one announced by the U.S. Coast and Geodetic Survey in 1959.

III  ·  History

How the center moved.

The center of a country is not fixed. When the country changes shape, the balance point moves with it.

  1. 1918 Forty-eight states: Kansas. The Coast and Geodetic Survey balanced a cardboard cutout of the contiguous states on a pin. It balanced near Lebanon, Kansas, where a stone monument still marks the spot.
  2. 1959 Fifty states: South Dakota. With the admission of Alaska and Hawaii, the balance point moved hundreds of miles north and west, to the prairie north of Belle Fourche, at 44°58′N 103°46′W.
  3. 1962 The point is marked. A reference mark and benchmark were set at the actual center, on private ranch land, where they remain today.
  4. 2007 A monument in town. Belle Fourche unveiled a granite compass rose, ringed by state flags, beside the Tri-State Museum, giving visitors an easy place to stand at the center of the nation.
IV  ·  The Monument

Center of the Nation Monument, Belle Fourche.

Because the true center lies in a working pasture, Belle Fourche built its monument in town. A 21-foot compass rose of South Dakota granite, encircled by the flags of the fifty states, sits beside the Tri-State Museum & Center of the Nation Visitor Center.

It is the place most travelers come to stand at the middle of the country — easy to reach, open year-round, and a short drive from Spearfish and Interstate 90.

V  ·  The Marker

The actual point.

The true center lies about twenty miles north of Belle Fourche, in open rangeland in Butte County.

A flag flies over the site, and survey markers are set into the ground beneath it. Around them is nothing but shortgrass prairie, sagebrush, and the long horizon of western South Dakota.

The land is private and grazed by cattle. The owners have chosen to leave it as it is, which is part of its appeal: the center of the nation looks very much as it did when it was first measured.

A note on private land

The marker stands on a working ranch. Visitors have long been tolerated, but please treat it as someone's home: close any gate you open, keep clear of livestock, and leave nothing behind.

VI  ·  Directions

Finding the center.

  1. From Interstate 90, take exit 10 at Spearfish and drive north on US 85 about ten miles to Belle Fourche.
  2. In Belle Fourche, visit the monument at 415 Fifth Avenue, two blocks north of the railroad tracks.
  3. For the actual point, continue north out of town into Butte County, about twenty miles, and follow the ranch road out to the marked site.
  4. The last stretch is gravel and then on foot across open pasture. Expect wind, cactus, and cattle.

Before you go

There are no services beyond Belle Fourche. Bring water, sturdy shoes, and a full tank. After rain, gravel roads can be difficult. The visitor center can confirm current conditions.

VII  ·  The Region

The Northern Black Hills.

The center sits where the Great Plains meet the northern edge of the Black Hills, one of the great road-trip regions of the country.

Spearfish and Spearfish Canyon

A short drive south of Belle Fourche. The canyon's scenic byway winds past limestone walls and waterfalls into the hills.

Devils Tower

America's first national monument rises from the plains just across the Wyoming line, an easy day trip from the center.

Deadwood and Sturgis

The Gold Rush town of Wild Bill Hickok and Calamity Jane, and the home of the summer motorcycle rally.

Mount Rushmore

In the heart of the Black Hills, south of Rapid City, about two hours from the center.

VIII  ·  Photography

From the air.

The view on the opening page looks down on the middle of the continent. The ring at its center marks 44°58′N 103°46′W, just east of where Montana, Wyoming, and South Dakota meet.

Drone photography of the marker and the surrounding prairie is coming soon.
