90th meridian west

In Antarctica, the meridian defines the western limit of Chile's territorial claim. The land further west is not claimed by any nation. The meridian also defines the western limit of the Lima, Antofagasta, Santiago, Puerto Montt and Punta Arenas flight information regions.

The 90th meridian west forms a great ellipse with the 90th meridian east, located midway between the Prime meridian and the 180th meridian; thus, the center of the Western Hemisphere is on this meridian.

In the United States, the Mississippi River runs close to the 90th meridian, crossing the meridian several times. The cities of St. Louis, Memphis and New Orleans are all close to the meridian.

One of the four 45 x 90 points is located in Rietbrock, Wisconsin, where the 45th parallel north intersects with the 90th meridian west, marking the halfway point between the 90° Latitude North, 180th Meridian East & West, 0° latitude, and 0° longitude.
