Everest: a Comparative Study of Height and Human Achievement 19222004 EVEREST: A COMPARATIVE STUDY OF HEIGHT AND HUMAN ACHIEVEMENT INTRODUCTION Mount Everest, the highest point on Earth, lies , m above sea level on the border of Nepal and China. 9 Towering , m above Aconcagua in Argentina, the next tallest peak, and over times the height of the 7 4 3 tallest man-made freestanding structure above sea-level, the CN Tower in Canada, Everest has remained the benchmark of achievment of mankind’s triumph over nature. At the end of the climbing season, humans have successfully summitted a total of , times while Everest claimed lives. rough a careful study of fatality rate on the routes to summit Everest, a timeline detailing events leading 1 to the rst successful ascent to the summit, a height and geographic comparison of Everest to the most 5 prominent peaks in the world, and a timeline tracking human architectural progress, judge for yourself the winner of the competition between human and nature. 18 ROUTES TO ASCEND EVEREST Routes are traced in black, with line-width in proportion to the number of successful summits, and transparency in proportion to the fatality rate (calculated by fatalities / summits); the more summits, the wider the line, the higher the fatality rate, the darker the line. A detailed gure breakdown appears below for each of the 18 routes (numbered in chronological order).

    “Before the practice, mountains are mountains, during the practice, mountains are not mountains, and after the realization, mountains are mountains” – Zen Master Seigen University of Alberta Metaphor and Ecocriticism in Jon Krakauer’s Mountaineering Texts by Alicia Aulda Jewett A thesis submitted to the Faculty of Graduate Studies and Research in partial fulfillment of the requirements for the degree of Master of Arts in Comparative Literature Office of Interdisciplinary Studies ©Alicia Aulda Jewett Fall 2012 Edmonton, Alberta Permission is hereby granted to the University of Alberta Libraries to reproduce single copies of this thesis and to lend or sell such copies for private, scholarly or scientific research purposes only.

The author reserves all other publication and other rights in association with the copyright in the thesis and, except as herein before provided, neither the thesis nor any substantial portion thereof may be printed or otherwise reproduced in any material form whatsoever without the author's prior written permission. Abstract This study examines Jon Krakauer’s three mountaineering texts, Eiger Dreams, Into the Wild, and Into Thin Air, from an ecocritical perspective for the purpose of implicating literature as a catalyst of change for the current environmental crisis. Language, as a means of understanding reality, is responsible for creating and reinforcing ethical ways of understanding our relationship with nature. Krakauer’s texts demonstrate the dangers of using metaphor to conceive nature by reconstructing the events of Chris McCandless’ journey to Alaska, his own experience climbing The Devil’s Thumb, and the 1996 disaster that occurred during his summit of Mount Everest.

  • Thirteen Nations on Mount Everest John Cleare 9
    Thirteen nations on Mount Everest John Cleare In Nepal the 1971 pre-monsoon season was notable perhaps for two things, first for the worst weather for some seventy years, and second for the failure of an attempt to realise a long-cherished dream-a Cordee internationale on the top of the world. But was it a complete failure? That the much publicised International Himalayan Expedition failed in its climbing objectives is fact, but despite the ill-informed pronouncements of the headline devouring sceptics, safe in their arm-chairs, those of us who were actually members of the expedition have no doubt that internationally we did not fail. The project has a long history, and my first knowledge of it was on a wet winter's night in 1967 at Rusty Baillie's tiny cottage in the Highlands when John Amatt explained to me the preliminary plans for an international expedi­ tion. This was initially an Anglo-American-Norwegian effort, but as time went by other climbers came and went and various objectives were considered and rejected. Things started to crystallise when Jimmy Roberts was invited to lead the still-embryo expedition, and it was finally decided that the target should be the great South-west face of Mount Everest. However, unaware of this scheme, Norman Dyhrenfurth, leader of the successful American Everest expedition of 1963-film-maker and veteran Himalayan climber-was also planning an international expedition, and he had actually applied for per­ mission to attempt the South-west face in November 1967, some time before the final target of the other party had even been decided.

  • Nepal 1989 a V Saunders
    AV SAUNDERS (Plates 25-27) These notes have been arranged in (more or less) height order. The intention has been to report developments and first ascents completed during the year, rather than to list repeat ascents of existing routes. 1989 was not a good year. There were few new routes, and several fatalities. On Everest (8 848m), reports ofovercrowding have become common­ place; this year they have been linked to outbreaks ofviral flu. As if this were not enough, there are now perennial arguments about the fixing of the route through the Khumbu icefall. Apparently the earlier expeditions who set up a route often demand payment from the-following expeditions who use the route. During the spring season, the Polish expedition organized by Eugeniusz Chrobak followed a variation on the W ridge route, avoiding the normal Lho La approach. Following a line with minimum avalanche danger, the team climbed Khumbutse (6640m) before descending to the Rongbuk glacier, where they established Camp I at 5850m. The line continued left of previous ascents to gain the W shoulder. Five more camps were established on the ridge and in the Hornbein Couloir. On 24 May Chrobak and Andrzej Marciniak reached the summit. Over the next two days they descended, stripping the camps with the help of two other team members. They reached Camp I in deteriorating weather to join another team arriving from base. The next day all the climbers set out for base, up the 600m fixed ropes over Khumbutse. At 1pm the six climbers were struck by an avalanche which broke the ropes.

  • The Effect of Giant Lateral Collapses on Magma Pathways and the Location of Volcanism
    Originally published as: Maccaferri, F., Richter, N., Walter, T. R. (2017): The effect of giant lateral collapses on magma pathways and the location of volcanism. ‐ Nature Communications, 8. DOI: http://doi.org/10.1038/s41467‐017‐01256‐2 ARTICLE DOI: 10.1038/s41467-017-01256-2 OPEN The effect of giant lateral collapses on magma pathways and the location of volcanism Francesco Maccaferri1, Nicole Richter1 & Thomas R. Walter1 Flank instability and lateral collapse are recurrent processes during the structural evolution of volcanic edifices, and they affect and are affected by magmatic activity. It is known that dyke intrusions have the potential to destabilise the flanks of a volcano, and that lateral collapses may change the style of volcanism and the arrangement of shallow dykes. However, the effect of a large lateral collapse on the location of a new eruptive centre remains unclear. Here, we use a numerical approach to simulate the pathways of magmatic intrusions underneath the volcanic edifice, after the stress redistribution resulting from a large lateral collapse. Our simulations are quantitatively validated against the observations at Fogo vol- cano, Cabo Verde. The results reveal that a lateral collapse can trigger a significant deflection of deep magma pathways in the crust, favouring the formation of a new eruptive centre within the collapse embayment. Our results have implications for the long-term evolution of intraplate volcanic ocean islands. 1 German Research Centre for Geosciences (GFZ), Potsdam, 14473, Germany.

It was, claimed Eric Shipton famously, “a veritable orgy of moun­ tain climbing.” In May 1935, Britain’s best mountaineers, including Shipton, longtime climbing partner Bill Tilman, plus 15 Sherpas, among them a 19-year-old novice, Tenzing Norgay, embarked from Darjeeling on the fourth-ever Mt. Everest expedition. In large part because no expedition book was later penned by Shipton, their 27-year-old leader, the 1935 Everest Reconnaissance Expedi­ tion has remained largely unknown and unlauded. No more! Seven decades later, The Forgotten Adventure reveals the never-before-told climbing adventures of three of the twentieth-century mountaineerings most revered icons reveling in the Himalayan glory of their youth.
