Mexico - April 13th, 2009

The Isthmus of Tehuantepec is an isthmus in Mexico that represents the shortest distance between the Gulf of Mexico and the Pacific Ocean. Geographically, the isthmus divides North America from Central America.

The isthmus includes the southeastern parts of Veracruz and Oaxaca, which are on the west, as well as small areas of Chiapas and Tabasco, which are east of the isthmus. Here, part of the Yucat√°n Peninsula can also be seen to the right.

The Isthmus of Tehuantepec is 200 km (125 miles) across at its narrowest point from gulf to gulf, or 192 km (120 miles) to the head of Laguna Superior on the Pacific coast. The both coasts of the isthmus are relatively free of sediments, while that of the peninsula is not.

The Sierra Madre breaks down at this point into a broad, plateau-like ridge, whose elevation, at the highest point reached by the Tehuantepec railway at Chivela Pass, is 224 m (735 ft).

The northern side of the isthmus is swampy and densely covered with jungle, as can be observed from its green and brown colors.
