(known in Mexico as Sierra Madre de Chiapas
) is a mountain range (located at ) which runs northwest-southeast from the state of Chiapas
and into El Salvador
. Most of the volcanoes
of Guatemala are a part of this range.
A narrow coastal plain lies south the range, between the Sierra Madre and the Pacific Ocean
. To the north lie a series of highlands and depressions, including the Chiapas Depression
, which separates the Sierra Madre from the Chiapas Plateau
, the Guatemalan Highlands
, and Honduras' interior highlands.
It is known near Guatemala city as the Sierra de las Nubes, and enters Mexico as the Sierra de Istatan. Its summit is not a well-defined crest, but is often rounded or flattened into a table-land. The direction of the great volcanic cones, which rise in an irregular line above it, is not identical with the main axis of the Sierra itself, except near the Mexican frontier, but has a more southerly trend, especially towards El Salvador; here the base of many of the igneous peaks rests among the southern foothills of the range. It is, however, impossible to subdivide the Sierra Madre into a northern and a volcanic chain; for the volcanoes are isolated by stretches of comparatively low country; at least thirteen considerable streams flow down between them, from the main watershed to the sea. Viewed from the coast, the volcanic cones seem to rise directly from the central heights of the Sierra Madre, above which they... Read More
