S. Quinteros the traditional P. palluma and P. patagonicus species groups but also a still not fully understood unsuspected diversity. Several populations in northern and southern Argentina may represent independent lineages that deserve formal description. Two of these populations were studied for the present contribution and are easily distinguished from all the other species in the genus. One of these populations is from Río Negro province and belongs to the P. patagonicus group; it exhibits a unique dorsal color pattern and several individuals are melanic, a characteristic never reported before for the genus, with the exception of P. tenebrosus. A careful examination of melanic individuals revealed the same dorsal pattern as that of non-melanic ones, although it is obscured. We also report the discovery of melanic individuals of two other species that are probably closely related: P. ceii and P. sitesi. The melanism found in the P. -

THE USPALLATA ARCHAEOLOGICAL PROJECT, ARGENTINA Course ID: ARCH XL159 June 1–July 1, 2017 DIRECTOR: Dr. Erik J. Marsh, CONICET. Laboratorio de Paleo-Ecología Humana & Universidad Nacional de Cuyo, Mendoza, Argentina ([email protected]) INTRODUCTION The Uspallata Valley in Mendoza, Argentina lies below the snow-peaked Andes. The valley has been occupied since the Late Pleistocene. It includes 1) the site Agua de la Cueva, which dates to over 13,000 years ago and is earliest human occupation of this part of the Andes, 2) Mendoza’s densest concentration of prehispanic rock art at Cerro Tunduqueral, and 3) the southernmost extension of the vast Inca Empire and its road system, including a high-altitude child sacrifice on Mount Aconcagua, the highest peak in the Americas. The project’s research focuses on the translation from foraging to pastoralism and agriculture. Both practices were present in the valley in the first millennium AD, but the timing and nature of the transition are unclear. This is most likely when the rock art at Cerro Tunduqueral was engraved, but this connection has not yet been demonstrated. We will investigate to what extend people remained people as they added novel subsistence strategies. These issues will be addressed with 1) survey data from a large area called Uspallata Norte (~8 km2) that includes dense and extensive surface dispersals of ceramics, ground stone, and expedient lithic tools and 2) excavations of a high altitude rock shelter, Paramillos. Both sets of data will complement the data from the 2016 field school, which excavated a surveyed and excavated rock shelter around Cerro Tunduqueral. -

It's also the second highest aspect of the expedition, of the illustrious Seven Summits. Of the highest points on each of the world’s continents, please contact us by only Everest gives a higher vantage point. However, despite all the impressive statistics, telephone: you can summit Aconcagua without any previous roped-climbing experience – but you will need previous experience of high altitude trekking or mountaineering and will need +44 (0) 114 276 3322 to add lots of hill-walking/hiking closer to home too before you head off to Argentina. Alternatively, please email Aconcagua lies entirely within Argentina, although close to the border with Chile, the us via our website: spine of the Andes dividing the continent between these nations. The usual approach to www.jagged-globe.co.uk Aconcagua is from the south following the valley of the Rio Horcones. This circles the western flank of the mountain and arrives at the Plaza de Mulas base camp at 4,365m. We visit the South Face on the way. Our route to the summit starts from Plaza de Mulas, where we spend several nights and days as we acclimatise. To improve 1 acclimatisation, and for the fun of it, we climb a satellite of Aconcagua, Bonete Peak (5,004m). The “normal route” from the Horcones Valley gives the most trusted means of reaching the top. -
Multi-Isotopic and Morphometric Evidence for the Migration Of

Durán1,2 & Valeria Cortegoso1,2 We present isotopic and morphometric evidence suggesting the migration of farmers in the southern Andes in the period AD 1270–1420, leading up to the Inka conquest occurring ~ AD 1400. This is based on the interdisciplinary study of human remains from archaeological cemeteries in the Andean Uspallata Valley (Argentina), located in the southern frontier of the Inka Empire. The studied samples span AD 800–1500, encompassing the highly dynamic Late Intermediate Period and culminating with the imperial expansion. Our research combines a macro‑regional study of human paleomobility and migration based on a new strontium isoscape across the Andes that allows identifying locals and migrants, a geometric morphometric analysis of cranio‑facial morphology suggesting separate ancestral lineages, and a paleodietary reconstruction based on stable isotopes showing that the migrants had diets exceptionally high in C4 plants and largely based on maize agriculture. Signifcantly, this migration infux occurred during a period of regional demographic increase and would have been part of a widespread period of change in settlement patterns and population movements that preceded the Inka expansion. -
Geo-Climatic Hazards in the Eastern Subtropical Andes: Distribution, Climate Drivers and Trends Iván Vergara1, Stella M
Geo-climatic hazards in the eastern subtropical Andes: Distribution, Climate Drivers and Trends Iván Vergara1, Stella M.

Detecting and understanding historical changes in the frequency of geo-climatic hazards (G-CHs) is crucial for the quantification of current hazards and project them into the future. Here we focus in the eastern subtropical Andes (32-33° S), using meteorological data and a century-long inventory of 553 G-CHs triggered by rainfall or snowfall. We first analyse their spatio-temporal distributions and the role of climate variability on the year-to-year changes in the number of days per 15 season with G-CHs. Precipitation is positively correlated with the number of G-CHs across the region and year-round; mean temperature is negatively correlated with snowfall-driven hazards in the western (higher) half of the study region during winter and with rainfall-driven hazards in the eastern zone during summer. The trends of the G-CHs frequency since the mid-20th century were calculated taking cautions for their non-systematic monitoring. The G-CHs series for the different triggers, zones and seasons were generally stationary. Nonetheless, there is a small positive trend in rainfall-driven G-CHs in 20 the eastern zone during summer congruent with a rainfall increase there. -
Geopolitical Representations: Chile and Argentina in the Campos De Hielo Sur1
Karen Isabel Manzano Iturra/Geopolitical representations: Chile and Argentina Geopolitical representations: Chile and Argentina in the Campos de Hielo Sur1 Representaciones geopolíticas: Chile y Argentina en Campos de Hielo Sur Karen Isabel Manzano Iturra* Received: March 11, 2015. Approved: October 1, 2015. Abstract From a concept first articulated by Rudolf Kjellén in 1917, geopolitics has continuously evolved up to the present. The incorporation of the initial representation has been of vital importance in the analysis of different territorial conflicts. Through a geopolitical analysis, this article aims to understand the geopolitical representations in the area of the Campos de Hielo Sur, the last boundary issue that remains pending between Chile and Argentina, in addition to the manner in which both countries have debated this issue, on the basis of a number of representations in which maps have generated the image of one state facing the other, thus privileging competition between them. Keywords: geopolitics, representation, conflict, maps, image. Resumen La geopolítica, desde el concepto acuñado en 1917 por Rudolf Kjellén, ha estado en continua evolución hasta el día de hoy. Desde la incorporación de las representaciones, la primera ha sido de vital importancia en los análisis de diferentes conflictos territoriales. A través de un análisis geopolítico es que en el presente artículo se pretende comprender las representaciones geopolíticas en la zona de Campos de Hielo Sur, el último problema de límites que aún se mantiene en suspenso entre Chile y Argentina y el cómo es que ambos países han discutido el problema a partir de una serie de representaciones en las que los mapas han constituido la imagen del uno frente al otro, privilegiándose de este modo la competencia entre los Estados. -

LOS CAMINOS INTERNACIONALES DE LA CORDILLERA a MEDIADOS DEL Slglo X1X (1852 -1863)
PEDRO S. MARTÍNEZ LOS CAMINOS INTERNACIONALES DE LA CORDILLERA A MEDIADOS DEL SlGLO X1X (1852 -1863) l. INTRODUCCIÓN a) Antecedentes coloniales de los siglos XVI y XVII DURAJ\"TE EL PERíoDO HISPÁNICO fue una cuestión clave en las rela ciones políticas, puesto que la región de Cuyo (fonnada por las ac tuales provincias argentinas de Mcndoza, San Juan y San Luis) perte necía a la jurisdicción de la Capitanía General de Chile. También in teresaba desde el punto de vista socioeconómico por tres motivos: a) porque los indios de Cuyo, encomendados a los españoles residentes en Chile, debían atravesar la cordillera para trabajar en el país tra sandino; b) porque la ruta era necesaria para el tránsito de los esclavos que llegaban procedentes de Buenos Aires; c) para facilitar el traslado de efectos y productos procedentes de Cuyo o de otros lugares del Vi rreinato rioplatense. Las vicisitudes y alternativas de la colonización -tanto en la región tucumana y platense, como en Chile- incidieron en las comunicaciones entre ambas regiones. La primera ruta continental fue inaugurada por el gobernador de Chile Alonso de Sotomayor cuando viajó desde Buenos Aires a Santiago en 1583. Este hecho y la segunda fundación de Buenos Aires por Juan de Garay en 1580, abrieron nuevas perspectivas comer ciales, tanto para el Río de la Plata como para Chile y Paraguay. Este itinerario fue el que se usó hasta los primeros años del siglo XVlI, en que las autoridades chilenas se preocuparon en buscar otro camino más directo. De 1604 procede el primer infonne conocido sobre el descu brimiento de un nuevo camino, debido al capitán Juan de L.'mea, ve cino de San Juan.
