Decían que sur de la gobernación del Perú, había una tierra rica en metales preciosos. Diego de Almagro, junto a una tropa de 2500 hombres españoles e indígenas de apoyo, llegó a los pies de la cordillera de los Andes en 1536. Recorrieron durante meses el inhóspito y frio paisaje buscando los metales esperados, avanzando hasta el valle de Copiapó. Almagro y sus hombres regresaron al Cuzco por el desierto de Atacama. No habían encontrado oro u otra cosa que les pareciera valiosa, y los costos del viaje habían acabado con las ilusiones de riqueza de estos conquistadores. Durante la travesía de regreso por suelo chileno, unos nativos del poblado de Chiu Chiu les fabricaron herraduras para que pudieran seguir adelante. Fueron las de primeras herraduras de Chile. Eran de cobre…

Since the Arab oil embargo of 1974, it has been clear that the days of almost limitless quantities of low-cost energy have passed. In addition, ever worsening pollution due to fossil fuel consumption, for instance oil and chemical spills, strip mining, sulphur emission and accumulation of solid wastes, has, among other things, led to an increase of as much as 10% in the carbon dioxide content of the atmosphere in this century. This has induced a warming trend through the 'greenhouse effect' which prevents infrared radiation from leaving it. Many people think the average planetary temperatures may rise by 4°C or so by 2050. This is probably true since Antarctic ice cores evidence indicates that, over the last 160000 years, ice ages coincided with reduced levels of carbon dioxide and warmer interglacial episodes with increased levels of the gas in the atmosphere. Consequently, such an elevation of temperature over such a relatively short span of time would have catastrophic results in terms of rising sea level and associated flooding of vast tracts of low-lying lands. Reducing the burning of fossil fuels makes sense on both economic and environmental grounds. One of the most attractive alternatives is geothermal resources, especially in developing countries, for instance in El Salvador where geothermal energy provides about a fifth of total installed electrical power already. In fact, by the middle 1980s, at least 121 geothermal power plants were operating worldwide, most being of the dry steam type.

This reprint, originally published in 1983, draws attention to the important lines of thought that have emerged during the past several decades to offer a portrait of contemporary physical geography which have been drawn together in this text. It introduces conventional terms and topics of the subject and weaves them into a conceptual fabric that rests on three major themes, including the energy-balance concept; a model for understanding the forces and processes in the landscape; the stress-threshold concept; the relationship between the stress produced by forces such as wind and water and the resistance of the earth's materials; and the magnitude and frequency of change in the landscape. Chapter summaries are featured along with numerous illustrations.
