Note the tip of the Juncal Glaciar at the bottom of the photograph. Looking north, along the glistening Juncal River, through the Mardones Valley to Mt. Aconcagua. Laguna del Inca, of the Portillo Ski Resort, is in the upper left.
Frederic and Dorthy Marmillod, a Swiss couple, had extensive experience climbing in the Valley of Juncal during the 1950’s. In Chapter 2 of their biography, they describe in great detail and incredible photography their fascinating first ascent in 1939 of Alto Los Leones (5445 m, 5380 m, 5400 m) and its 2500 m high vertical face, with the Chilean climber Carlos Píderit.

Federico Reichart on Alto de los Leones
“El Alto de los Leones, de 5400m y ubicado al interior de Río Blanco, ha despertado el interés de montañeros desde muy temprano. El famoso Federico Reichert, quien exploró y escaló numerosos cerros en esa zona, en su obra maestra le dedica un párrafo muy especial (“Auf Berges und Lebenshöhe”, pag 252):
“Dirigiéndonos hacia el norte, los ojos se detienen por una aparición de aspecto fascinante, ocasionado por la arquitectura agreste y los colores sombríos de las torres del Cerro Los Leones, situado al otro lado del divortium en territorio chileno. En forma de paredes lisas e inaccesibles, se levanta esta magnífica montaña, dominando como obelisco gigantesco todo el valle Juncal chileno. Acorazado por todas partes por paredones casi verticales de mas de 1100 mts. de altura, el Cerro Los Leones, que puede figurar como simbolo de las llanuras chilenas precordilleranas, nunca perderá su virginidad, pues la accesibilidad de su cumbre nos parece quedar fuera del limite de lo posible”.
From Mountaineering in Chile, by Jill Neates
” firstly comes the Grupo Alto del Rio Blanco, headed by Leòn Negro and Leòn Blanco. South of this group is Nevado Juncal which is the point from which springs a great network of peaks reaching almost to the streets of Santiago. To the north-west, bounded by the Rio Blanco and Rio de los Leones, is the Rio Blanco group, dominated by Alto de los Leones, one of the cordillera’s most formidable peaks, itself overlooked by Nevado Juncal.”
“One of the earliest scientific visitors to this part of the Andes was the naturalist Charles Darwin who, in March 1835, travelled from Santiago up the Yeso valley, over the Piuquenes and Portillo passes to Mendoza, returning via the easier Uspallata Pass just south of Aconcagua. This trip, mainly made on horseback, lasted twenty-four days and resulted in the first scientific geological survey of central Chile. Other scientists, employed by the Chilean government, were the French and Polish geologists Amadée de Pissis and Ignaz Domeyko, who was the first to attempt the ascent of Tinguiririca. In 1831 F.L.J. Meyen almost reached the crater edge on Maipo, a climb which was completed by the German mountaineer Paul Gűssfeldt in 1883. In 1895 the Germans G. Brand and R. Lűck climbed El Plomo, the peak on which was subsequently found the mummified body of a sacrificial victim. In 1897 Stuart Vines and Mathias Zurbriggen, members of Edward Fitzgerald’s Aconcagua expedition, made the laborious but easy ascent of Tupungato. By this time the Chilean Boundary Commission had been set up, under the direction of the eminent Chilean geographer Luis Riso Patròn, charged with mapping the boundaries with Bolivia and Argentina, a task which filled the years 1895-1909. Riso Patròn himself participated in the field-work, helping to place iron markers (mojons) on border passes upto 5000 metres high and, in the Cordillera Central, ascending the volcano Tupungatito. In 1924 Riso Patròn published his famous Diccionario Geogràfico de Chile, a work of great merit and erudition which contains 28,215 Chilean geographical names.
“In 1906 the German scientist Frederick Reichert, who worked for the Argentine government, turned his attention to the section of the Andes lying between Aconcagua and Tupungato. His previous expeditions had been to the Puna de Atacama, and in 1914 he was to make the first of his visits to Patagonia. During the intervening years, usually with the Swiss engineer Robert Helbling as his climbing companion, he discovered, explored and mapped the Juncal group, which has some very large glaciers, as well as making first ascents of several high peaks, including Leòn Blanco, Cerro Doris, Nevado del Plomo and Nevado Juncal. Further south he explored and climbed Polleras and Tupungato; all his expeditons were made from the Argentine side.
Reichert and Helbling were enthusiastic climbers. Leaving their mules and arrieros in camp, the pair would carry their sleeping-bags and other gear up as high as 5500 metres, where they would bivouac in the intense cold. Next day they would try for their peak. They climbed together but had an ‘each man for himself’ agreement – if one man had to turn back, the other went on; if one wanted to stay behind for a second attempt, the mules and men were divided between them. The ascent of Nevado Juncal was one of their major climbs. After several days of careful reconnaissance, they left camp at an altitude of 4200 metres and, after overcoming enormous seracs and walls of ice, bivouaced under an icefall at the foot of the north ridge (c.5200m). After the usual very cold night, they gained the ridge up steep snow and through a complicated system of crevasses. The ridge was followed without difficulty to the summit which was reached in mid-afternoon. Descending through the night they arrived back at their tent twelve hours later.”
“At this time European settlers in Chile were beginning to take up the sporting challenge of the Andes. In 1912 two Englishmen, H. Trewhela and R. Temperley, together with the Italian Felix Mondini, climbed La Paloma, one of the peaks seen to such advantage from the streets of Santiago. Shortly before, the Germans had started a sports organization, the Deutscher Ausflugsverein, in Valparaiso and had begun making ascents. In 1924 the Germans created another section of the Deutscher Ausflugsverein in Santiago, while in 1922 the organization had commenced publication of Andina, the first South American mountaineering journal. In 1933 the Club Andino de Chile was set up, also a German creation; thereafter Chileans gradually became active in the sport and the publicity given to the first ascent in 1939 of the difficult Alto de los Leones did much to popularize local mountaineering. Today there are many climbing and skiing clubs, most of which are affiliated to the national organization, the Federaciòn de Andinismo y Excursionismo de Chile which is responsible, among other things, for the provision of mountain huts. ”
