476 the AMERICAN ALPINE JOURNAL Glaciers That Our Access Was Finally Made Through the Mountain Rampart
476 THE AMERICAN ALPINE JOURNAL glaciers that our access was finally made through the mountain rampart. One group operated there and climbed some of the high-grade towers by stylish and demanding routes, while the other group climbed from a hid- den loch, ringed by attractive peaks, north of the valley and intermingled with the mountains visited by the 1971 St. Andrews expedition (A.A.J., 1972. 18: 1, p. 156). At the halfway stage we regrouped for new objec- tives in the side valleys close to Base Camp, while for the final efforts we placed another party by canoe amongst the most easterly of the smooth and sheer pinnacles of the “Land of the Towers,” while another canoe party voyaged east to climb on the islands of Pamiagdluk and Quvernit. Weather conditions were excellent throughout the summer: most climbs were done on windless and sunny days and bivouacs were seldom contem- plated by the parties abseiling down in the night gloom. Two mountains may illustrate the nature of the routes: Angiartarfik (1845 meters or 6053 feet; Grade III), a complex massive peak above Base Camp, was ascended by front-pointing in crampons up 2300 feet of frozen high-angled snow and then descended on the same slope in soft thawing slush: this, the easiest route on the peak, became impracticable by mid-July when the snow melted off to expose a crevassed slope of green ice; Twin Pillars of Pamiagdluk (1373 meters or 4505 feet; Grade V), a welded pair of abrupt pinnacles comprising the highest peak on this island, was climbed in a three-day sortie by traversing on to its steep slabby east wall and following a thin 300-metre line to the summit crest. -

Zeh, Ph.D., Dean, Graduate School May, 2018 i ABSTRACT Textural and geochemical analysis of lavas and tephra from a poorly studied, glacially dissected, mafic, stratocone, Manantial Pelado, in the Southern Andean Volcanic Zone was collected to characterize the volcano’s petrogenesis and assess its primitive nature. Manantial Pelado lies within the transitional segment of the Southern Volcanic Zone (35.5°S) amidst thickened crust (~55 km) while surrounded by extensive silicic volcanism such as the Descabezado Grande-Cerro Azul Volcanic Complex. How mafic magmas reached the surface through thickened continental crust is a larger question at hand, but prior to addressing broader processes at work, initial geochemical characterization is necessary. Understanding the full extent of its primitive nature is crucial for broader insight of proximal vent interactions and relationships as well as insight towards magma genesis. -

Los Santuarios De Altura Incaicos Y El Aconcagua: Aspectos Generales E Interpretativos
ISSN 0325-2221 Relaciones de la Sociedad Argentina de Antropología XXIV. 1999. Buenos Aires. LOS SANTUARIOS DE ALTURA INCAICOS Y EL ACONCAGUA: ASPECTOS GENERALES E INTERPRETATIVOS Juan Schobinger (*) RESUMEN Se efectúa una somera revista de los materiales hallados en 1985 en el filo sudoccidental del contrafuerte "Pirámide " del Cerro Aconcagua en la provincia de Mendoza, a 5300 metros de altura. Se relaciona este enterratorio ritual incaico (niño de 7años, envuelto en numerosos textiles y rodeado de seis estatuillas) con otros sitios altoandinos que contenían momias conservadas por congelamiento. Se menciona su distribución, relación con los caminos que cruzaban la Cordillera, ocasión en que se realizaban (una forma especial de capacocha o sacrificio solemne de personas jóvenes, organizado por el Estado en sufaz religiosay eventualmente también política), y aspectos del simbolismo concomitante. Se señala la contribución de la arqueología de alta montaña para conocer mejor la cosmovisión andina, a través de las prácticas rituales asociadas a la veneración de las altas montañas dotadas de una especial sacralidad. Con las investigaciones de los últimos años se ha afianzado el reconocimiento de que el factor simbólico-religioso ha jugado un papel importante en la expansión imperial incaica. ABSTRACT Thispaper offers a briefreview ofthe archaeological evidencefound in 1985 at 5300 meters altitude in the southwestern edge of the «Pirámide» backdrop of the Aconcagua Mountain (province of Mendoza). This Inka ritual burial (a seven year oíd boy wrapped in numerous textiles and surrounded by six statuettes) is compared with other high Andes sites containingfrozen, and thus preserved, mummies. The paper discusses their distribution, their relation to the roads crossing the Cordillera, occasion during which they were placed there (a particular capacocha or solemn sacrifice ofyoung people, organized by the State as parí ofits religious componeñt or perhaps even political) and aspects of related symbolism. -

The first satellite-derived inventory of glaciers and rock glaciers in Chile, created from Landsat TM/ETM+ images spanning between 2000 and 2003 using a semi-automated procedure, is pre- sented in a single standardized format. Large glacierized areas in the Altiplano, Palena Province and the periphery of the Patagonian icefields are inventoried. The Chilean glacierized area is 23 708 ± 1185 km2, including ∼3200 km2 of both debris-covered glaciers and rock glaciers. -
