Chilean Notes, 1962-1963
CHILEAN NOTES ' CHILEAN NOTES, 1962-1963 BY EVELIO ECHEVARRfA C. (Three illustrations: nos. 2I-23) HE mountaineering seasons of I 962 and I 963 have seen an increase in expeditionary activity beyond the well-trodden Central Andes of Chile. This activity is expected to increase in the next years, particularly in Bolivia and Patagonia. In the Central Andes, \vhere most of the mountaineering is concen trated, the following first ascents were reported for the summer months of I962: San Augusto, I2,o6o ft., by M. Acufia, R. Biehl; Champafiat, I3,I90 ft., by A. Diaz, A. Figueroa, G. and P. de Pablo; Camanchaca (no height given), by G. Fuchloger, R. Lamilla, C. Sepulveda; Los Equivo cados, I3,616 ft., by A. Ducci, E. Eglington; Puente Alto, I4,764 ft., by F. Roulies, H. Vasquez; unnamed, I4,935 ft., by R. Biehl, E. Hill, IVI. V ergara; and another unnamed peak, I 5,402 ft., by M. Acufia, R. Biehl. Besides the first ascent of the unofficially named peak U niversidad de Humboldt by the East German Expedition, previously reported by Mr. T. Crombie, there should be added to the credit of the same party the second ascent of Cerro Bello, I7,o6o ft. (K. Nickel, F. Rudolph, M. Zielinsky, and the Chilean J. Arevalo ), and also an attempt on the un climbed North-west face of Marmolejo, 20,0I3 ft., frustrated by adverse weather and technical conditions of the ice. In the same area two new routes were opened: Yeguas Heladas, I5,7I5 ft., direct by the southern glacier, by G. -

Abstract This work aims to assess geothermal power potential in identified high enthalpy geothermal areas in the Chilean Andes, based on reservoir temperature and volume. In addition, we present a set of highly favorable geothermal areas, but without enough data in order to quantify the resource. Information regarding geothermal systems was gathered and ranked to assess Indicated or Inferred resources, depending on the degree of confidence that a resource may exist as indicated by the geoscientific information available to review. Resources were estimated through the USGS Heat in Place method. A Monte Carlo approach is used to quantify variability in boundary conditions. -

[email protected] * Permanent address: Juan Moya 910, Ñuñoa, Santiago, Chile. ABsTracT. Newly described outcrops, excavations and sediment cores from the region of Última Esperanza, Magalla- nes, contain tephra derived from the large late-glacial explosive R1 eruption of the Reclús volcano in the Andean Austral Volcanic Zone. New radiocarbon dates associated to these deposits refine previous estimates of the age, to 14.9 cal kyrs BP (12,670±240 14C yrs BP), and volume, to >5 km3, of this tephra. The geographic and stratigraphic distribution of R1 also place constraints on the evolution of the ice-dammed proglacial lake that existed east of the cordillera in this area between the termination of the Last Glacial Maximum (LGM) and the Holocene. -

The Timing, Dynamics and Palaeoclimatic Significance of Ice Sheet Deglaciation in Central Patagonia, Southern South America
The timing, dynamics and palaeoclimatic significance of ice sheet deglaciation in central Patagonia, southern South America Jacob Martin Bendle Department of Geography Royal Holloway, University of London Thesis submitted for the degree of Doctor of Philosophy (PhD), Royal Holloway, University of London September, 2017 1 Declaration I, Jacob Martin Bendle, hereby declare that this thesis and the work presented in it are entirely my own unless otherwise stated. Chapters 3-7 of this thesis form a series of research papers, which are either published, accepted or prepared for publication. I am responsible for all data collection, analysis, and primary authorship of Chapters 3, 5, 6 and 7. For Chapter 4, I contributed datasets, and co-authored the paper, which was led by Thorndycraft. Detailed statements of contribution are given in Chapter 1 of this thesis, for each research paper. I wrote the introductory (Chapters 1 and 2), synthesis (Chapter 8) and concluding (Chapter 9) chapters of the thesis. Signed: ..................................................................................... Date:.............................. (Candidate) Signed: ..................................................................................... Date:.............................. (Supervisor) 2 Acknowledgements First and foremost, I am very grateful to my supervisors Varyl Thorndycraft, Adrian Palmer, and Ian Matthews, whose tireless support, guidance and, most of all, enthusiasm, have made this project great fun. Through their company in the field they have contributed greatly to this thesis, and provided much needed humour along the way. For always giving me the freedom to explore, but wisely guiding me when required, I am very thankful. I am indebted to my brother, Aaron Bendle, who helped me for five weeks as a field assistant in Patagonia, and who tirelessly, and without complaint, dug hundreds of sections – thank you for your hard work and great company. -

Patagonia Luxury Hiking Excursion
Patagonia Luxury Hiking Excursion Please note that all of the itineraries listed in our web site are actual private tour itineraries we have prepared for clients over the past 12-18 months. By the very nature of what we do, each private tour itinerary is custom, exclusive and unique unto itself. Our over-riding goal is to create lifelong memories that you and your family will forever carry deep within your hearts. Overview Though our past hikes on the Milford Track (New Zealand), Inca Trail (Machu Picchu), Glacier (U.S.), and various areas of Switzerland and Austria were particularly memorable, we must confess that the hiking, horseback riding, and spectacular setting of, relatively inaccessible, Patagonia is unparalleled. The critical contrast is Patagonia’s pristine remoteness: no mass tourism or crowded hiking trails here! When hiking the wide range of areas in Patagonia, it is easy to see how this vast landscape still has hundreds of unnamed mountains, with many points inaccessible and unexplored. Located at the tip of the South American continent, the outstanding national parks (Torres del Paine!) and private reserves stretch across Chile and Argentina, divided by the Andes Mountains. The features of Patagonia are remarkable: wild rivers, muddy rainforests, glaciated peaks, granted monoliths, and vast steppes. This is a place for reflection, deep solitude, and unforgettable outdoor activities.

En el caso especial de las erupciones explosivas, generalmente este procedimiento involucra trabajos detallados sobre el volumen y la distribución de los materiales de caída. El presente trabajo realiza una revisión bibliográfica que abarca 177 contribuciones publicadas desde principios del siglo 20 hasta los más recientes del 2015, con el fin de definir conceptos, metodologías y modelos que permitan aproximar cálculos realistas de la cantidad de material emitido en depósitos de tefra, los errores más comunes y los aspectos que ayudan a describir y caracterizar estos depósitos de acuerdo a sus componentes. -
