Correspondence to: Alvaro Ayala ([email protected]), now at Centre for Advanced Studies in Arid Zones (CEAZA) Abstract (max 250 words). As glaciers adjust their size in response to climate variations, long-term changes in meltwater production can be expected, affecting the local availability of water resources. We investigate glacier runoff in the period 15 1955-2016 in the Maipo River Basin (4 843 km2), semiarid Andes of Chile. The basin contains more than 800 glaciers covering 378 km2 (inventoried in 2000). We model the mass balance and runoff contribution of 26 glaciers with the physically-oriented and fully-distributed TOPKAPI-ETH glacio-hydrological model, and extrapolate the results to the entire basin. TOPKAPI- ETH is run using several glaciological and meteorological datasets, and its results are evaluated against streamflow records, remotely-sensed snow cover and geodetic mass balances for the periods 1955-2000 and 2000-2013. -
Volcán Tupungatito
Volcán Tupungatito Región: Metropolitana Provincia: Cordillera Comuna: San José de Maipo Coordenadas: 33°23’S – 69°50’O Poblados más cercanos: El Alfalfal – los Maitenes – El Manzano Tipo de volcán: Estratovolcán Altura: 5603 m s.n.m. Diámetro basal: 7,5 km Área basal: 44 km2 Volumen estimado: 30 km3 Volcán Tupungatito. Vista desde el noroeste Última actividad: 1986 (Fotografía: Carolina Silva, SERNAGEOMIN) Última erupción mayor: 1959-1960 Ranking de riesgo 22 específico: Generalidades El volcán Tupungatito corresponde a un estratovolcán de corta vida (< 80 ka) y reducido volumen. Está emplazado en el extremo septentrional de la Zona Volcánica Sur de los Andes, a 75 km al este de Santiago. Forma parte de un grupo volcánico donde destacan los volcanes Tupungato y Nevado Sin Nombre, ambos inactivos. Durante su fase inicial este volcán registró una importante actividad efusiva, con generación de coladas de lava de hasta 18 km de alcance encauzadas en torno al valle del río Colorado, además de lahares, flujos piroclásticos y avalanchas de detritos de mediano alcance. Durante el Holoceno su actividad cambió a un estilo mixto (efusivo/explosivo), donde además de las coladas de lava se tiene registro de erupciones mayoritariamente vulcanianas. Este aumento en la actividad explosiva ha construido un sistema cratérico hacia la cumbre del volcán, el cual se localiza cercano a una depresión semi-circular de 4 km de diámetro rellena por un glaciar. En la actualidad exhibe actividad fumarólica intensa y permanente concentrada en uno de estos cráteres el cual, además, hospeda un lago ácido. Registro eruptivo Los registros de erupciones mencionan una veintena de eventos desde el siglo XVII, los que incluyen reactivaciones menores e incrementos en la actividad fumarólica. -

Abstract. Rhyolitic pyroclastic flows and tephra from the al., 1984) and Calabozos (300 and 150 ka; Hildreth et al., Pleistocene (450 ± 60 ka) eruption of the Laguna Diamante 1984) calderas have also been well documented. Here we caldera comprise the largest volume of pyroclastic material present preliminary results from a study in progress of late in northwest Mendoza Province. However, trace-element Pleistocene and Holocene tephra deposits in the province data indicate that 1-3 meter thick rhyolite tephra deposits, of Mendoza, Argentina. These results indicate that large which outcrop on both the southwest (Cacheuta) and late Pleistocene tephra deposits around the city of northeast (Borbollon) margins of the city of Mendoza, have Mendoza were not derived from the 450 ka Laguna an independent origin. These chemical data, and Diamante eruption, but from multiple younger eruptions of preliminary chronology, imply at least two different large some other source, and that numerous Holocene tephra late Pleistocene eruptions, both younger than that of the Diamante caldera, possibly of Tupungato volcano or the deposits outcropping along the Andean precordillera Tupungatito caldera. -

This 25-day program is made up of 19 expedition days, with rest days between expeditions. The program is subject to modification depending on weather conditions and the physical conditions and capacities of the participants. The program includes all costs related to the expedition: El Programa incluye todos los gastos relacionados a la expedición. -Transportation, logistics, food, guide, donkeys and/or porters. The program does not include hotels, transportation within the metropolitan region or Copiapó, and other costs outside of the expedition. Program: Ojos Del Salado Volcano is the world’s highest active volcano, at 6893 meters, well-known for its impressive and foreboding height. Located in the Atacama desert, near the Argentinian border, this mountain is not very technically challenging, but it’s meteorological conditions make it a great challenge for any mountaineer. This program is designed with the end goal of summiting the Ojos Del Salado Volcano, with appropriate acclimatization built in. Chronogram. The expedition begins in the mountains nearby to Santiago, Chile, Cerro El Pintor (4.180 m). This mountain is a natural lookout to Cerro El Plomo (5.424 m). This first mountain will be summited in a single day. Cerro El Pintor Our next objective is the Cerro El Plomo (5.424 m) the “apu” (guardian) of the central Mapocho valley chosen by the Incas and holds a lot historical importance. In 1954, the famous El Plomo Mummy was discovered here, at an altitude of 5,000 meters. This expedition will take us 5 days, beginning and ending in Santiago. Cerro el Plomo from El Pintor After our expedition to El Plomo, we will enter the heart of the Cajon del Maipo where we will set our sights on the most southern 6,000 meter mountains in the Andes and in the world, El Marmolejo (6,100m).This mountain neighbors Argentina, and is the tallest peak in the region, with expansive views of all of the valleys that course through the Cajón Del Maipo. -

Annex 36 Survey of High Mountain Activities in the San José De Maipo Commune
ANNEX 36 SURVEY OF HIGH MOUNTAIN ACTIVITIES IN THE SAN JOSÉ DE MAIPO COMMUNE 1 INTRODUCTION The purpose of this survey is to describe the main attractions that the commune of San José de Maipo has to offer in terms of mountain activities and adventure sports. The survey, which is by no means exhaustive, is based on publicly-available information on the localities in the direct area of influence of the Project. More specifically, the information on high mountain activities in San José de Maipo needed for the survey was obtained from municipal agencies and the internet, mainly from the websites of tourist agencies operating in the area. The activities and the areas where these activities take place are discussed in the following sections. 2 MAIN ACTIVITIES The main mountain activities of the commune of San José de Maipo are: mountaineering, climbing, hiking, trekking, and skiing. In general, these activities take place in the upper basins of the Colorado, El Volcán and Yeso rivers, and include: Colorado river basin: walking, hiking, rambling, horseback riding, and adventure sports, such as mountaineering, trekking, sport climbing and traditional climbing. El Volcán river basin: walking, hiking, rambling, and adventure sports, such as mountaineering, trekking, randonee skiing, sport climbing, and traditional climbing and ice climbing. Yeso river basin: mountaineering, trekking and ice climbing.

BACKGROUND AND PROJECT DESCRIPTION Introduction 2.1 The Alto Maipo Hydroelectric Project (Proyecto Hidroeléctrico Alto Maipo – “PHAM” or “the Project”) consists of the construction and operation of two run-of- the-river hydroelectric facilities with a combined capacity of 531 MW (Alfalfal II, with a capacity of 264 MW and Las Lajas, with a capacity of 267 MW) located approximately 50 km east of Santiago, Chile (see Figures 1 and 2). The two plants will use the waters of the upper basin of the Yeso and Volcán rivers, as well as the waters of the middle and lower course of the Colorado River in the Commune or Municipality of San José de Maipo. 2.2 The PHAM will capture flow from four tributaries to the Volcán River, the Yeso River, the Aucayes Stream, and the Colorado River (via the existing Alfalfal I and Maitenes Hydropower Plants), all of which are tributaries to the Maipo River, to operate the Alfalfal II and Las Lajas powerhouses in series prior to discharging to the Maipo River. -
