| '''Land of [[Guatemala]]'''
| |
|
| |
| Guatemala is bounded to the north and west by Mexico, to the northeast by Belize and (along a short coastline) by the Gulf of Honduras, to the east by Honduras, to the southeast by El Salvador, and to the south by the Pacific Ocean.
| |
|
| |
| '''Relief'''
| |
|
| |
| The surface of Guatemala is characterized by four major topographical features. Southern Guatemala is dominated by a string of 27 volcanoes extending for about 180 miles (300 km) between Mexico and El Salvador. Between the volcanoes and the Pacific Ocean lies a fertile plain ranging 25–30 miles (40–50 km) in width. The Petén region, a large, low-lying, rectangular area, juts northward to occupy a portion of the Yucatán Peninsula, a limestone platform shared with Mexico and Belize. Sandwiched between the volcanic landscape and the Petén are the high mountain ranges and valleys. These arc gently eastward from Mexico for a distance of 210 miles (340 km), extending into northern Honduras.

|
| |
| The volcanic region of Guatemala consists of three elements: a row of volcanoes of geologically recent origin, flanked by a deeply eroded volcanic tableland of older origin to the north and the narrow coastal plain constructed of volcanic debris on the Pacific slope. The alignment of volcanic cones begins with the Tacaná Volcano (13,428 feet [4,093 metres]), located on the frontier with Mexico, and continues eastward across Guatemala into El Salvador. Among these are three continuously active volcanoes: the growing summit of Santiaguito (8,202 feet [2,500 metres]) located on the southern flanks of Santa María (12,375 feet [3,772 metres]); Fuego (12,582 feet [3,835 metres]); and Pacaya (8,371 feet [2,552 metres]). The highest peak is Tajumulco (13,845 feet [4,220 metres]). The city of Antigua Guatemala is precariously situated beneath three volcanoes: Agua Volcano (12,350 feet [3,760 metres]), Fuego Volcano (12,336 feet [3,763 metres]), and Acatenango Volcano (13,045 feet [3,976 metres]). Lava flow from Pacaya is sometimes visible from Guatemala City.

|
| |
| From the base of the volcanic row, at an elevation of about 1,500 feet (450 metres), the Pacific coastal plain gradually slopes south to sea level at the shoreline of the ocean. The plain extends east-west for a distance of about 150 miles (240 km) and is one of the country’s richest agricultural areas. Three-fourths of the population and most of the major cities are concentrated in the volcanic region and the Pacific slope, and the volcanic eruptions and earthquakes characteristic of this area have repeatedly taken a heavy toll of property and life.
| |
|
| |
| The rugged and deeply dissected volcanic highlands, which lie to the north of the volcanic row, average 9,000 feet (2,750 metres) in elevation near the Mexican border and decline gradually to 3,000 feet (900 metres) at the opposite border with El Salvador. Ash-filled basins and scenic lakes are scattered throughout this region.
| |
|
| |
| The sierras provide a major barrier between the heavily occupied volcanic landscape to the south and the sparsely populated Petén to the north. Sierra los Cuchumatanes to the west rises to elevations in excess of 10,000 feet (3,000 metres). Eastward, the lower sierras of Chamá, Santa Cruz, Chuacús, Las Minas, and the Montañas del Mico are separated by deep valleys that open eastward on a narrow Caribbean shoreline.
| |
|
| |
| The Petén, lying largely below 1,000 feet (300 metres) in elevation, exhibits a knobby or hilly surface characterized by subsurface drainage of water. The region is replete with scattered lakes, Lake Petén Itzá being the largest. Extensive flooding takes place during the rainy season.
| |
|
| |
| '''Drainage'''
| |
|
| |
| The east-flowing Motagua River and west-flowing Cuilco pass in opposite directions through a structural trough that serves as the boundary between the volcanic terrain of southern Guatemala and the sierras of its midsection. The sierra region is drained by large rivers that flow primarily north into the Gulf of Mexico by way of the Usumacinta River. The 250-mile- (400-km-) long Motagua River is the longest of a series of rivers draining eastward toward the Caribbean. Several small rivers drain into the Pacific Ocean. Much of the Petén region is drained by the subsurface flow of water.
| |
|
| |
| '''Soils'''
| |
|
| |
| The volcanic belt of southern Guatemala contains some of the most productive soils; nevertheless, the northernmost sector of this region is particularly subject to erosion induced by the prevalence of steep slopes and deforestation. Within the sierra region, heavier rainfall—combined with centuries of cultivation of the thinner soils on the steep slopes and the wanton destruction of forests—has led to widespread erosion there too. The limestone surface of the Petén produces shallow and stony soils that are difficult to farm.

|
| |
| '''Climate'''
| |
|
| |
| Located within the tropics and with elevations ranging between sea level and more than 13,000 feet (4,000 metres), Guatemala experiences a diversity of climates. Below 3,000 feet (900 metres) in elevation, average monthly temperatures range between 70 and 80 °F (21 and 27 °C) throughout the year; between 3,000 and 5,000 feet (900 and 1,500 metres), temperatures range between 60 and 70 °F (16 and 21 °C); and from 6,000 to 9,000 feet (1,500 to 2,700 metres), they range between 50 and 60 °F (10 and 16 °C). Above 9,000 feet, temperatures are marginal for crops, but the grazing of animals is possible.
| |
|
| |
| Near-desert conditions prevail in the middle section of the Motagua River valley, whereas precipitation in excess of 150 inches (3,800 mm) occurs at higher elevations of the Pacific-facing volcanic row and on the north- and east-facing slopes of the sierras. In general, a dry season prevails between November and April; however, moisture-laden trade winds from the Caribbean yield rainfall throughout the year on north- and east-facing slopes. An average of 40 to 80 inches (1,000 to 2,000 mm) of precipitation is received in southern and eastern Guatemala, but this is doubled in areas located nearer the Caribbean shoreline.
| |
|
| |
| Severe tropical storms, especially during the months of September and October, often deluge the country with damaging floods. Strong winds accompanying these storms, as well as winter invasions of cold air, occasionally place crops at risk. Hurricane Mitch, one of the deadliest tropical cyclones ever in the Atlantic Ocean, which brutally struck nearby Honduras and Nicaragua in October 1998, also caused extensive damage in Guatemala, displacing nearly 100,000 people.

| |
| '''Plant and animal life'''
| |
|
| |
| In the Petén, a dense rainforest is interspersed with patches of savanna grasslands. The sierras are forested with oak and pine. In the volcanic highlands, stands of pine, fir, and oak have been largely destroyed except on the highest slopes. On the Pacific coastal plain, the landscape largely has been cleared of its tropical forest and savanna.
| |
|
| |
| The richest variety of animal life inhabits the lowland forest areas, although some species, such as deer, monkeys, peccaries, tapirs, ocelots, and jaguars, are increasingly rare. Among the reptiles of note are numerous snake species, crocodiles, and iguanas. The birdlife of the rainforests is particularly exuberant and includes the radiantly plumaged quetzal (Pharomachrus), the national bird, for which a reserve has been set aside in the sierras near Cobán.
