  • Radakovic and Chambers: High Andean Deglaciation
    RADAKOVIC AND CHAMBERS: HIGH ANDEAN DEGLACIATION High Andean deglaciation from the Pleistocene into the recent times and its effect on water quality from pyrite contamination. Radakovic, D. and Chambers, R. (2012). Supervisor: Cammeraat, L. H. Field course Geo-ecological Systems, University of Amsterdam. Abstract This study aims to investigate the surface areal extent of a tropical glacier close to Huaraz in the Cordillera Blanca, Peru from 18 000 years before present (BP) to 2011. This was completed by identifying glacial deposits and landforms in satellite images using the programs Google Earth and ArcGIS. The equilibrium line altitude (ELA) for these glaciers were calculated to range from 4500 – 4550m asl during the Pleistocene to 5050 -5100m asl in recent times. The glacier front is currently retreating at a rate of 85 100m2 (1.5%) per year, while in the Pleistocene it receded at a rate of 4800m2 (0.01%) per year. This deglaciation implies a significant increase in the ELA. Deglaciation also exposes more of the underlying bedrock to weathering and erosion. In this area pyrite (FeS2) is present in the bedrock in the Chicama formation and glacial tills, it is readily oxidised and dissolved into water to form iron hydroxides (Fe(OH)3) and sulphuric acid (H2SO4) which are harmful to humans and animals. This is a natural source of contamination for the local river, the Río Negro, so a link between lithology and water quality in sources is also tested here, as the water is used for drinking and agriculture in the Ollieros district, Peru. Glacial tills appear to be related with the cause for high concentrations of dissolved pyrite in the Río Negro.

  • Chapter 7 Glaciers
    CHAPTER 7 GLACIERS 1. INTRODUCTION 1.1 Before the era of universal air travel, which commenced less than half a century ago, few of the world’s population had seen a glacier. I suspect that majority of class members in this course have seen a glacier—if not close up, then out of a jetliner window. In the Canadian Rockies, you can drive to within almost a stone’s throw of the terminus of the Athabasca Glacier, a classic active valley glacier. In many other parts of the world, valley glaciers are accessible to even casual day hikers. The great ice sheets of the world, in Antarctica and Greenland, remain much less accessible. 1.2 In the broad context of geologic history, the Earth is in an “icehouse” time, with recurrent major ice-sheet advances across the Northern Hemisphere continents. (There have been several other such icehouse periods in Earth history, separated by long intervals of ice-free times, called “greenhouse” periods, with no evidence of glaciation.) The Earth has only recently emerged from the latest episode of continental glaciation. Does it surprise you to learn that a mere twenty thousand years ago the Boston area was beneath a mile of glacier ice moving slowly southward toward its terminus south of what is now the south coast of New England? 1.3 The Earth is in many senses a glacial planet: • 10% of the Earth is covered with glacier ice (about 15 million square kilometers). • About 40% of the Northern Hemisphere in winter is covered with solid water at any given time (land and sea).

  • Implications of Geomorphological Research for Recent and Prehistoric Avalanches and Related Hazards at Huascaran, Peru
    Nat Hazards (2009) 50:193–209 DOI 10.1007/s11069-008-9330-7 ORIGINAL PAPER Implications of geomorphological research for recent and prehistoric avalanches and related hazards at Huascaran, Peru Jan Klimesˇ Æ Vı´t Vilı´mek Æ Marek Omelka Received: 11 June 2008 / Accepted: 24 November 2008 / Published online: 13 December 2008 Ó Springer Science+Business Media B.V. 2008 Abstract Detailed research of superficial deposits below the northern peak of Huascaran (Cordillera Blanca) provides new information on the limits of a paleo-avalanche origi- nating from this mountain. Geomorphological mapping of the sediments identified glacial deposits, deposits from historical rock-debris avalanches and huge boulders from a paleo- avalanche. Schmidt Hammer rock-hardness tests were used to distinguish between the several generations of rock-debris avalanches, but largely failed to distinguish between the much older moraine and the paleo-avalanche sediments. Thus, only the field geomor- phological mapping proved to be reliable for identifying the limits of the paleo-avalanche. The limits identified as granite boulders deposited over volcanic rocks were found to extend 30 m further up the opposite valley slope than previously had been mapped. This larger extent implies a greater volume and/or greater mobility for the prehistoric event. Keywords Slope movements Á Natural hazards Á Schmidt Hammer tests Á Huascaran Á Cordillera Blanca Á Peru 1 Introduction The Cordillera Blanca in Peru is part of the highly tectonically active Andean mountain chain formed by collision of the Cocos, Nazca, Antarctic, and South American lithosphere plates. Intense endogenic processes form suitable conditions for highly active and dan- gerous geomorphic processes.

The map has been created as the necessary precursor for an improved understanding of the glacial history of the region, and to strengthen a program of dating glacial limits in the region. The map was produced using Landsat TM, ASTER DEM, Google Earth™ imagery and field validation. The different landforms which were mapped include: lateral moraines, terminal moraines, proglacial lakes, palaeo-cirques, erratic boulders, outwash plains, whale backs, glacial grooves, rochee mountanee, drumlins, glacial striations, hanging valleys debris/talus cones, subglacial material. Glacial-Geomorphological features are very significant for palaeo-climatic reconstruction, showing variations, temporally and spatially. At the same time these landforms, which are also altered by processes prevailing during interglacial period, helps in geo-environment studies. Keywords: Hanging valleys; Medial moraines; Terminal moraines; Liddar lows for a maximum length of 14 kms before it merges with Debris/talus cones; Remote sensing and GIS east Liddar at famous tourist spot Phalgam. The area reveals variegated topography due to the combined action of glaciers and rivers.

The District received the DAHP’s concurrence on August 8, 2011. Following a Cultural Resources Assessment of the proposed Project by the District’s consultant AMEC Environment & Infrastructure Inc. (AMEC), on February 21, 2012, the District requested DAHP’s concurrence with AMEC’s determination of “No Adverse Effects to Historic Properties” for the proposed Project. DAHP responded on February 28, 2012, stating agreement with the APE as mapped in AMEC’s report. The DAHP also concurred with AMEC that the current Project as proposed will have “NO ADVERSE EFFECT” on National Register eligible or listed historic and cultural resources. The District’s correspondence with DAHP, as well as AMEC’s report, are attached to this appendix.

  • Geomorphology and Natural Hazards of the Selected Glacial Valleys, Cordillera Blanca, Peru Jan Klimeš
    24 AUC Geographica AUC Geographica 25 GEOMORPHologY AND natural HAZARDS OF THE selected glacial valleYS, Cordillera Blanca, PERU JAN Klimeš Institute of Rock Structure and Mechanics, Academy of Sciences, p .r .i ., Prague ABstract Field reconnaissance geomorphologic mapping and interpretation of satellite data was used to prepare geomorphological maps of the selected glacial valleys in the Cordillera Blanca Mts., Peru. The valleys are located about 5 km apart, but show important differences in geology and landforms presence and distribution. Above all, the presence of small glacial lakes near the ridge tops is typical for the Rajucolta Valley, whereas no such lakes occur in the Pumahuaganga Valley. Detailed field assessment of possible hazardous geomorphological processes on the slopes around the Rajucolta and Uruashraju Lakes was performed. Shallow landslides and debris flows often channeled by gullies are the main dangerous processes possibly affecting the glacial lakes. In the case of the Rajucolta Lake, evidences of shallow landslides were also found. Mapping showed that newly formed small glacial lakes and moraine accumulations located on the upper part of the valley slopes may be source of dangerous debris flows and outbursts floods in the future. In some cases, those processes may affect glacial lakes on the main valley floor, which often store considerable amount of water.T hus the possibility of triggering large glacial lake outburst flood should be carefully evaluated. Key words: geomorphologic map, natural hazards, glacial lakes, Peru, Cordillera Blanca 1.
