Este centro deportivo me había honrado con el nombramiento de Presidente Honorario y me exigió que dictase una conferencia en la velada pública que a tal fin estaba organizando el Ateneo de Caracas. Gustosamente accedí a ello, haciendo un recuento histórico del desarrollo del alpinismo mundial. He creído que su publicación puede ser interesante y útil no sólo a los deportistas sino también a todas aquellas personas amantes de la naturaleza, especialmente a aquellas que se dedican al estudio de las Ciencias con ella relacionadas.

The data compiled from the Cascades and Aleutians are compared to geologic, geochemical and geophysical information from productive volcanic arc centers in the other parts of the world. Seven other volcanic arc segments from around the globe are used in this comparative study. Preliminary findings from data evaluation indicate that there are systematic changes in structural setting, from an extensional influ- ence south of Mt. Hood (in part due to encroachment of the back arc in the southern half) to more compressional north of Mt. Hood. Comparison with productive geothermal fields around the world shows that large fumarolic areas are associated with most >240°C power-producing geothermal systems outside the US arcs (e.g., Kamojang, Indonesia, among others), whereas there is a general absence of large fumarolic areas in the Cascades and Aleutian arcs, aside from of the Lassen volcano area. -
The South American Indian As a Pioneer Alpinist
TI-lE SOUTH AMERICAN INDIAN AS A PIONEER ALPINIST 81 THE SOUTH AMERICAN INDIAN AS A PIONEER ALPINIST BY EVELIO ECHEVARRfA C. ECENTL Y it has become kno\vn that a number of very high Andean mountain tops had not only been ascended but also permanently occupied by the Indians, possibly as much as three centuries before de Saussure's ascent of Mont Blanc. They climbed peaks of up to 22,ooo ft., they constructed shelters on or near their tops, and they used the high places as watch-towers or as sacrificial shrines. Some authorities believe that this activity took place as early as the late four teenth century, though we cannot prove that some of it did not take place long after, possibly as late as the nineteenth century. These Indian accomplishments have been left unmentioned in practi cally all mountaineering history books. In this article, which may be the first to attempt a comprehensive survey,1 my purpose is to review briefly the location and the nature of each discovery. The area in which these Indian mountain ascents took place is what in physical geography is known as the Atacama desert (although this name is nowadays used in political and cultural geography for a much more restricted area). It is a treeless, sandy and volcanic waste-land seldom visited by mountaineers. It stretches from the neighbourhood of Arequipa, in Peru, as far south as Elqui in Chile; to the east it reaches the Andean slopes that face the jungles of Argentina and Bolivia, and to the west, the Pacific Ocean. -

Hoyas Hidrográficas De Chile: Segunda Región
HOYAS HIDROGRÁFICAS DE CHILE: SEGUNDA REGIÓN REALIZADO POR: HANS NIEMEYER F. HOVA DEL RlO LOA La hoya hidrográfica del río Loa~ con una superf! cie tota~'de 33 570 km2 , se desarrolla en el tercio norte de la IIa R~ gión de Chile, entre latitudes extremas 20Q52' y 22Q57' L.S. ylongit~ des 68QOO' y 7oQ02' L.o. El río Loa nace en la falda norte del Vn. Mi ño~ en los Ojos del Hiño, casi en los límites entre la la y IIa Regio nes de Chile, en 21Q15' L.S. y 70Q L.O~ Su longitud total se acerca a 440 km. A pesar de su extensa hoya, los recursos h!dricos provienen de la cuenca alta que comprende alrededor del 20% de la su~ perficie total. Con curso aproximadamente norte-sur~ el Loa reco rre casi 150 km en un profundo cañón de altura variable, desde su nací miento hasta el oasis de Chiu ~hiu, pueblo que se levanta en su margen izquierda. En este trayecto recibe sus dos tributarios más importantes que le caen del este: el río San Pedro o Inacaliri y el río Salado. En Chiu Chiu dobla su curso sensiblemente hacia el oeste para alcanzar en un recorrido de 115 km el punto denominado Chacance. En él se le reúne por la derecha el río San Salvador. En Chacance,el Loa toma franca di= recci6n sur-norte hasta fertilizar el oasis de Quillagua, despu~s de una trayectoria de 80 km. A partir de Quillagua el Loa describe un gran arco y luego desemboca en el Pacífico~ en Caleta Huel~n, despu~8 de trasponer el macizo costero en un tajo profundo~ de más de 500 m de al tura. -

We have determined concentrations of H2O, major, trace and volatile (S, Cl) elements by EPMA and SIMS from melt inclusions and groundmass glasses of the 1986, 1853 and prehistoric explosive eruptions of basaltic magmas from the Chikurachki volcano, northern Kurile arc. Melt inclusions are hosted by olivine (Fo72–78), orthopyroxene (mg#=72–75), clinopyroxene (mg#=71–77) and plagioclase (An74–96) phenocrysts. Estimated crystallization conditions were in the range from 910 to 1180 8C at less than 400 MPa total pressure and oxygen fugacity of NNO+1 to +2 log units. Inclusion glasses are basaltic to andesitic in composition. -

Ebeko is an active volcano on Paramushir Island, northern Kuril Islands, showing characteristic Vulcanian-type activity. In 2019, we started a comprehensive survey using a combination of field station records and repeated unoccupied aircraft system (UAS) surveys to describe the geomorphological features of the edifice and its evolution during ongoing activity. Seismic data revealed the activity of the volcano and were complemented by monitoring cameras, showing a mean explosion interval of 34 min. Digital terrain data generated from UAS quadcopter photographs allowed for the identification of the dimensions of the craters, a structural architecture and the tephra deposition at cm-scale resolution. The UAS was equipped with a thermal camera, which in combination with the terrain data, allowed it to identify fumaroles, volcano-tectonic structures and vents and generate a catalog of 282 thermal spots. The data provide details on a nested crater complex, aligned NNE-SSW, erupting on the northern rim of the former North Crater. -

The only maps in which very many of the places mentioned in the following notes can be found are the Admiralty Charts, numbered 2128 and 240o.* Any one wlio compares these notes and charts, tlie originals of which were drawn by Captain H. J. Snow, with the scanty literature and imperfect maps previously existing, will at once recognize how very much has been accom- plished by the patience and perseverance of an individual. New rocks and shoals have been indicated, whilst supposed dangers of a like character have been removed. The position of islands have been corrected relatively and in longitude, whilst anchorages* tide rips, watering-places, sea-lion and seal rookeries, have been located and described. The shortest route between Vancouver and certain ports on the Asiatic coast has been freed from un- certainties and dangers, while Canadian-Pacific steamers, whalers, and a large fleet of pelagic hunters have now harbours of refuge opened which may be approached with comparative safety. In short, after shipwrecks, risks, and dangers, the escapes from which have often seemed incredible, independently of the geological, natural history, and general scientific notes which have been collected, Captain H. J. Snow, whilst sacrificing by his publica- tions his own professional interests as a hunter, has entitled himself to recognition from all who navigate and patrol the fog-bound shores of the rocky Kurils.
