50 Archaeological Salvage at El Chiquirín, Gulf Of
50 ARCHAEOLOGICAL SALVAGE AT EL CHIQUIRÍN, GULF OF FONSECA, LA UNIÓN, EL SALVADOR Marlon Escamilla Shione Shibata Keywords: Maya archaeology, El Salvador, Gulf of Fonseca, shell gatherers, Salvage archaeology, Pacific Coast, burials The salvage archaeological investigation at the site of El Chiquirín in the department of La Unión was carried out as a consequence of an accidental finding made by local fishermen in November, 2002. An enthusiast fisherman from La Unión –José Odilio Benítez- decided, like many other fellow countrymen, to illegally migrate to the United States in the search of a better future for him and his large family. His major goal was to work and save money to build a decent house. Thus, in September 2002, just upon his arrival in El Salvador, he initiated the construction of his home in the village of El Chiquirín, canton Agua Caliente, department of La Unión, in the banks of the Gulf of Fonseca. By the end of November of the same year, while excavating for the construction of a septic tank, different archaeological materials came to light, including malacologic, ceramic and bone remains. The finding was much surprising for the community of fishermen, the Mayor of La Unión and the media, who gave the finding a wide cover. It was through the written press that the Archaeology Unit of the National Council for Culture and Art (CONCULTURA) heard about the discovery. Therefore, the Archaeology Unit conducted an archaeological inspection at that residential place, to ascertain that the finding was in fact a prehispanic shell deposit found in the house patio, approximately 150 m away from the beach. -

Guatemala es un país extraordinariamente dotado de una belleza natural, pero pocas personas conocen que Los primeros registros de la cultura Maya se ubican en esto se debe en gran medida, a eventos que se la época Preclásica que da inicio aproximadamente en conocen hoy como hecatombes. Por ejemplo, el lago de el año 1500 (A. de C.) La cosmovisión de los mayas, Atitlán en Sololá es el resultado de un evento de origen reflejo en ese entonces de su relación con eventos volcánico de enorme magnitud. Este evento destructivos, evidenciándose esto en creencias como la denominado por los vulcanólogos como la erupción de destrucción de mundos anteriores por diluvios... los Chocoyos, ocurrió hace aproximadamente 85 mil De “Ixchel” una de las deidades mayas se señala años, y significó la expulsión de más o menos 150 que aparece también como la personificación del agua metros cúbicos de material, llegando a alturas de 50 como elemento de destrucción, de las inundaciones y kilómetros, que cubrieron un radio de cien kilómetros torrentes de lluvia. En el Popol Vuh se cita a con al menos tres metros de material expulsado. Se “Cabracan”, Dios que se encargaba de sacudir las calcula que las cenizas llegaron más allá de Panamá o montañas grandes y pequeñas, evidenciando la La Florida en Estados Unidos. Este evento de enorme percepción de ciertos fenómenos como provenientes de violencia cambio la geografía de nuestro territorio y designios divinos, fuera del alcance humano, rasgos como constancia dejo un cráter de aproximadamente 1 que pueden identificarse aún hoy en día y que kilómetro de profundidad que hoy ocupa el Lago de constituyen factores de la vulnerabilidad actual en Atitlán. -

Mapping Environmental Services in Highland Guatemala Public Disclosure Authorized
PES Learning Paper 2007-4 Mapping Environmental Services in Highland Guatemala Public Disclosure Authorized Stefano Pagiola, Wei Zhang, and Ale Colom Public Disclosure Authorized Public Disclosure Authorized December 2007 Public Disclosure Authorized Latin America and Caribbean Sustainable Development Department World Bank Washington DC, USA Abstract This paper uses data from Guatemala to map areas that are important for the provision of indirect ecosystem services—services whose benefits are enjoyed at some distance from the ecosystem that provides them, such as watershed services (enjoyed downstream) or biodiversity conservation (enjoyed globally). These services are usually externalities from the perspective of land users, and so tend to be under-provided. Mapping the areas that supply such services links the supply and demand of ecosystem services in a spatially explicit way, allows the identification and prioritization of areas of conservation interest. Authors Stefano Pagiola is senior environmental economist and Wei Zhang is consultant in the Environment Department, World Bank. Ale Colom is an independent consultant. Keywords Environmental services, mapping, watershed, biodiversity, Guatemala Acknowledgements Work on this paper was financed in part by a grant from the Norwegian Trust Fund for Environmentally and Socially Sustainable Development.

Volcanism and Geochemistry in Central America: Progress and Problems M
Volcanism and Geochemistry in Central America: Progress and Problems M. J. Carr1, M.D. Feigenson1, L. C. Patino2 and J.A. Walker3 1Department of Geological Sciences, Rutgers University 2Department of Geological Sciences, Michigan State University 3Department of Geology and Environmental Geosciences, Northern Illinois University Most Central American volcanoes occur in an impressive volcanic front that trends parallel to the strike of the subducting Cocos Plate. The volcanic front is a chain, made of right-stepping, linear segments, 100 to 300 Km in length. Volcanoes cluster into centers, whose spacing is random but averages about 27 Km. These closely spaced, easily accessible volcanic centers allow mapping of geochemical variations along the volcanic front. Abundant back-arc volcanism in southeast Guatemala and central Honduras allow two cross-arc transects. Several element and isotope ratios (e.g. Ba/La, U/Th, B/La, 10Be/9Be, 87Sr/86Sr) that are thought to signal subducted marine sediments or altered MORB consistently define a chevron pattern along the arc, with its maximum in Nicaragua. Ba/La, a particularly sensitive signal, is 130 at the maximum in Nicaragua but decreases out on the limbs to 40 in Guatemala and 20 in Costa Rica, which is just above the nominal mantle value of 15. This high amplitude regional variation, roughly symmetrical about Nicaragua, contrasts with the near constancy, or small gradient, in several plate tectonic parameters such as convergence rate, age of the subducting Cocos Plate, and thickness and type of subducted sediment. The large geochemical changes over relatively short distances make Central America an important margin for seeking the tectonic causes of geochemical variations; the regional variation has both a high amplitude and structure, including flat areas and gradients. -
