  ARGENTINA AND CHILE, CENTRAL
ULTRA-PROMINENCES

22 Mountain Summits with Prominence of 1,500 meters or greater

 Please send comments to webmaster.

Compiled 2005-06 by Jonathan de Ferranti with assistance from John Biggar and Aaron Maizlish.

This is one of eight lists that cover the known ultra-prominences for South America.  This project represents original research into accurate elevations and prominence of the world's major summits, employing both new data sources and published topographic materials.  Parts of South America have notoriously poor information on summit elevations - values found in publication and on the internet for a given summit frequently vary by several hundred meters.  We  strive to more accurately represent elevations through interpretation of a variety of resources, including our own interpolation methods of SRTM data (see also theory section.)

South America has 208 ultra-prominences (13.6% of the world's total).  118 of these summits are in Chile and/or Argentina.  These have been segmented into three lists, as follows:

Argentina and Chile North:  Andes region north of Aconcagua.  This includes the Puna de Atacama, and the provinces of Northern Argentina.  Note that three of the summits on the North list also appear on the Bolivia list.

Argentina and Chile Central (on this page):  The northern border of this region is the low saddle, Hito Paso de la Iglesia, near the major road and rail pass connecting Santiago, Chile to Mendoza, Argentina.  This is the key saddle for Cerro Tupungato (#1 on that list).  The 22 peaks on the Central list represent the Andes between Tupungato and the region near Puerto Montt.

Argentina and Chile South (Patagonia):  The northern border of this region is a low broad saddle near the town of Epuyén, Argentina.  This represents a line running approximately from Puerto Montt, Chile east to the Rio Chubut in Argentina.  There are an impressive 52 known ultras in the Southern region, including four island highpoints. 

For those of you interested in matters of national pride; there are 78 summits in Chile or on its borders, which ranks fifth among the nations of the world.  There are 58 summits in Argentina or on its borders, which ranks seventh in the world.  (18 summits are believed to lie exactly on the Chile/Argentina border.)  Such is the nature of prominence that deeply carved glacial landscapes are favored when the summits are also high:  Chilean Patagonia, British Columbia and Alaska have a significant amount of the world's ultra-prominent summits.

[12] Sierra Velluda.  Our analysis indicates that this is much higher than the published 3385 meter elevation.

[14] Picos de Barroso.  Our analysis indicates that this is probably higher than the published 5113 meter elevation.

[17] The summit of Choshuenco is called Volcan El Mocho, another summit named V. Choshuenco is slightly lower.   V. Choshuenco is also spelled V. Shoshuenco.

[22] V. Lonquimay.  Our analysis indicates that this is much higher than the published 2726 meter elevation.
