Geographic description

The Highlands lie between 6360 ft and 13780 ft and are made up of a series of high valleys enclosed by mountains. There are volcanoes which are both active and extinct. The local name for the region is Altos, meaning "highlands."

The relief of the mountainous country which is north of the Highlands and drains into the Atlantic is varied by terraces, ridges, and underfalls. Its general configuration is compared by E. Reclus to the appearance of "a stormy sea breaking into parallel billows". A range called the Sierra de Chamá travels eastward towards Belize and is connected by low hills with the Cockscomb Mountains. The Sierra de Santa Cruz, a similar range, continues east to Cape Cocoli between the Polochic and the Sarstoon rivers. A third, the Sierra de las Minas, or its eastern portion, Sierra del Mico, stretches between the Polochic and the Motagua rivers. Between Honduras and Guatemala, the frontier is formed by the Sierra de Merendón.

A few of the streams of the Pacific slope actually rise in the highlands pushing through the Sierra Madre at the bottom of deep ravines. A large river, the Chixoy or Salinas River, flows northwards towards the Gulf of Mexico. In addition to the streams which break through to the Pacific, a number of larger streams which drain to the Gulf of Mexico or the Caribbean Sea have their sources in the highlands. The Motagua River, whose principal head stream is called the Rio Grande, has a course of about 400 kilometres (250 mi), and is navigable to within 140 km (90 mi) of Guatemala City which is situated on one of its confluents, the Rio de las Vacas. It empties in the Gulf of Honduras, an arm of the Caribbean. Of similar importance is the Polochic River, which is about 290 km (180 mi) in length, and navigable about 32 km (20 mi) above the river-port of Telemán. A vast number of streams, among which are the Chixoy, Lacantún, and Ixcán, unite to form the Usumacinta River, which passes along the Mexican frontier, and flows on through Chiapas and Tabasco into the Bay of Campeche. The Grijalva and its tributaries the Cuilco and San Miguel rivers drain west into the Chiapas Depression and from there into the Gulf of Mexico. Lake Atitlan is a land-locked basin encompassed with lofty mountains. About 14 km (9 mi) south of Guatemala City lies Lake Amatitlán and the town of Amatitlán.
