Cordillera Raura

John Ricker

The following is a chapter from a guidebook in preparation on the Peruvian Andes. Maps and photographs are used especially to establish the positions of mountain features and to give local place names on Quechua and Spanish. Much confusion in the geography of the Cordillera Raura (and of the Peruvian Andes in general) has originated from the misnaming of peaks and the use of inappropriate foreign language place names, even when local names exist. Future visitors are encouraged to seek out and use native place names.

Ascents and route information, where known, are kept brief to enable alpinists and alpine tourists to continue in the Andean tradition to make their own climbing and route-finding decisions.

CHAINS of deep blue lakes, open swampy green valleys, rock and glacier-mantled peaks characterize the Cordillera Raura. In addition to natural beauty the popular press has made much of the fact that the Cordillera Raura is at the headwaters of three major tributaries of the Amazon, the Ríos Marañón, Huallaga, and Mantaro. The Río Marañón originates in the lakes Niñoqocha near Mina Raura.

Although the Raura is only 25 kilometers from north to south, there are many moderate and some extremely difficult climbs, with short approaches. However, none of these is as long as major routes in the world-renowned Cordillera Huayhuash situated just 10 to 15 kilometers to the northeast. Even though the Raura has been used to advantage by serious parties as training for both the Cordilleras Huayhuash and Blanca, these same parties have largely overlooked the extremely difficult routes on the highest peaks of the Cordillera Raura itself.

The serenity and beauty of the central portion of the cordillera has been broken by mining activity. Mina Raura, a lead-copper-silver mine, operates at an altitude in excess of 4600m. Rising stair-like from Cabal- loqocha a concentrator discharges evil wastes into the once blue lake. Above, the red roofs of the workers’ housing seem to stretch to the very ice of the mountains. The muffled boom of blasting accompanies one to the summit of Torre de Cristal. But only a day’s walk away, in one of the beautiful valleys, such as Laguna Surasaka, these aspects of the 20th century are forgotten. Rustic attempts are being made to extend workings at Mina Restauradora, at the head of the Quebrada Gaiko. Some of the ancient adits, once connected by tortuous llama trail to Mina Raura, are threatened by avalanche from the west face of Torre de Cristal. An abandoned concentrator site on the roadside just north of Quichas indicates former activity in the valley east of Quichas, while south and east of Oyón abandoned coal mines are now being reassessed.

The recorded history of exploration and climbing in the Cordillera Raura is far from complete. In 1906 the indefatigable Annie Peck ascended part of Nevado Santa Rosa’s northern glacier. O.M. Miller’s survey for the American Geographical Society disclosed initial mining activity at Laguna Santa Rosa in September 1927. It was proposed to pack out ore by llama to Oyón at that time. Jenks on his visit of June 1939 failed to see signs of activity at the mine while attempting the southeast ridge of Patrón Sudeste. Like Annie Peck he reconnoitered the long northern glacier of Nevado Santa Rosa, just failing to climb Pichuyqocha before returning to Cerro de Pasco by horse.

According to Jenks and Cardich, historically the term Raura refers to Nevado Santa Rosa and the Siete Caballeros. The name Gaiko, Jenks explained, was confined to the Patrón-Torre de Cristal massif. At present both groups are referred to as Cordillera Raura, especially since the mine has also adopted the name.

Since Jenks’ time a road has been built to Mina Raura and a permanent community established at ca. 4700m above sea level. Also the lovely Laguna Santa Ana has been drained to allow access to an ore body at the base of Matapaloma.

Glaciation

The Cordillera Raura is the southernmost of several major glaciated cordilleras north of the Tunshu group, Cordillera Central. Among spectacular features is the westerly-dipping ice plateau, Nevado Azuljanka (4800–5400m), which extends 10 km. to form the northern extremity of the range. The plateau rises eastward a maximum of 2½ km. in gentle undulations and a steep cliff wall marks its eastern margin. A tiny ice plateau is formed at the union of the Yarupáj-Torre de Cristal- Yanku ridges. Bulky-looking Nevado Santa Rosa supplies most of the remaining glacier ice. Permanent snow begins at about 5000m in the northern and central parts of the range, 5200m on the western outliers. Glacier limits extend down to ca. 5000m in the north, ca. 4850m on the east, 4750m on the western margin and ca. 4650m on the south sides. Glacier data on the map is based mainly on aerial photographs of 1962–63.

Climate and Weather

The climate is similar to that of the Cordillera Huayhuash. High- altitude climbing is almost always risky due to daily snowfall in the rainy season from January up to April. Also access roads can be washed out during this period. Settled weather is most likely from June through July, though climbers have been active at various times from April to December in some years; in others even the month of June has been stormy.

Geology

We are indebted to Dr. John Cobbings, Overseas Geological Surveys, London, England for the following “Summary of the Geology of the Cordillera Raura”.

The Cordillera Raura is a zone of eastward-thrusting fault plates. The high peaks of the Cordillera Raura, including Nevados Azuljanka, Rumiwayin, Yarupáj, Condorsenga, Santa Rosa, and the Siete Caballeros are parts of major anticlines trending north to north-west and are composed almost entirely of massive grey limestone of the Late Cretaceous Jumasha Formation. This rock varies from friable to fairly massive. The best rock climbing to date has been found on Nevado Condorsenga. At the road side on the west face of Condorsenga, numerous brachiopod and gastropod fossils are well-preserved.

The Celendin Formation (late Cretaceous) overlies the Jumasha and crops out near Patarqocha, and on the east side of Chuspiqocha. It consists of marls and limestones, extending south toward Tinkiqocha.

Parts of Nevados Torre de Cristal and Patrón, Cerro Yanku, and the Mina Raura itself border an intrusive zone of tonalite and quartz-diorite (probably early Tertiary).

The early Tertiary Calipuy Group includes andesitic to dacitic volcanic rocks, cropping out on the south-west side of Nevado Yarupáj massif and in the region of Laguna Putusay, north to Caballoqocha.

The Cordillera Raura straddles a major fault line between the miogeosyn- clinal basin fades of the Cretaceous to the west and the thinner anticlinal fades to the east. The fault line, unbroken along more than 160 km. of strike length, runs beneath the glacier at the eastern foot of Nevado Yarupáj and along the line of the Que brada Yanku.

Access

The most direct access is by road from Lima via Churin and Oyón (3637m). Normally it is a one-day journey by bus to Oyón. The bus remains overnight, setting out for Mina Raura (ca 4600m) early the next morning. A market and co-operative food store at the mine provide a wide variety of food. The Oyón approach can be extremely dangerous for unacclimatized climbers. Time to acclimatize can be gained by staying at Oyón for a few days, though even Oyón is initially too high for most people coming from the coast for the first time. Acclimatization camps at Quebrada Yanku (ca 4350m) or Laguna Surasaka (ca 4380m) would also be desirable before attempting to stay at Mina Raura.

Acclimatization at Cajatambo (3376m), 2 to 4 days walk west of the Cordillera Raura, would be easier than at Oyón. Cajatambo is also accessible by bus from Lima in one day. Yanahuanca (3184m), several days travel to the east of Cordillera Raura, can be reached only from Cerro de Pasco (ca 4300m), which is itself too high for proper initial acclimatization.

Peak Descriptions

Mountains are grouped arbitrarily in the following regions, separated from neighboring groups and other ranges by valleys, a pass or col: 1. The Azuljanka Ice Plateau Region. 2. Western Outliers of the Cordillera Raura. 3. Rumiwayin and Yarupáj Region. 4. Patron, Torre de Cristal and Gaiko Region. 5. Chirajanka and Antakallanka Region. 6. Siete Caballeros, Santa Rosa and Condorsenga Region. Peaks are listed within each zone from north to south where possible.

Place Names: Only indigenous place names are used in the text and on the accompanying map. Mountains are sometimes named for pastures, rivers, lakes, or settlements near them. Peaks are frequently known by different names from different valleys. Some of the alternate names are indicated in parentheses. Rivers and tributaries are often known by the names of the farms or settlements along their length so that the name of the river may change every few kilometers.

Considerable variation is to be found in the Quechua dialects of the highlands of Peru. The spelling system used is as much as possible in accordance with the proposals of the third Congreso Indigenista Inter- americano, in La Paz 1954; and the Centro de Investigación de Linguística Aplicada, Universidad Mayor de San Marcos, Lima, 1972. Symbols used are as follows. W is used instead of the Spanish HU. K in Quechua is used to indicate 3 equivalent letters in Spanish: K as in Kerosina, C as in canta, QU as in queso. The post-velar stop (or fricative) Q indicates an important consonant in Quechua not usually recognized by non-speak- ers and often confused with the velar K. The exact pronunciation of Q varies regionally and depends also on its position within a word. CCH is used to indicate an aspirated CH as in the word cheqchhi. No attempt has been made to record differences in vowel length at this time.

Definitions of terms in Spanish are given in the Map Legend. Qocha and Mayo are used in place of Laguna and Río respectively where local usage dictates.

Peak Heights: The capital letter “P” before an isolated height in the text designates a high point or peak without a local name. All precise

heights are taken from mapsheets published by the Instituto Geográfico Militar, and from mining maps. Approximate heights are indicated (ca.) and are not to be relied upon for precise determinations.

Grading: Grades, where indicated, reflect the judgment of the original ascent party in the U.I.A.A. system. Since climbing standards vary widely caution is needed in interpreting route difficulty. Individuals should keep in mind such variables as the ability of the party concerned to acclimatize, season of the climb, weather and snow conditions, and what kind of experience party members are likely to have had.

Climbing parties: Only first ascents and new routes are listed. Climbers are indicated in alphabetical order. Rope partners are grouped together where information is available.

1. AZULJANKA ICE PLATEAU REGION

Azuljanka (blue cold place) is the local name applied to the long undulating ice plateau at the north end of the Cordillera Raura from the west. The highest point (5421m) is designated specifically as Nevado Azuljanka in this chapter and also is known as “Kuajadajanka” from the east. The ice plateau can be reached most easily from Oyón and Laguna Surasaka. Pack animals are available only at Oyón. Regular transportation bypasses the road to Laguna Surasaka at the Río Quichas bridge.

NEVADOS PATRON—TORRE DE CRISTAL—GAIKO REGION

All these peaks are accessible from Mina Raura.

Nevs. Patrón 5236m to ca. 5275m All peaks were probably traversed by S. Jungmeier and H. Raditschnig, 25 July, 1957, from Mina Raura (RPA 3: 1956/57). The most likely route would be the SE slopes of Patrón SE (5236m) traversing over the central peak (ca. 5250m), NW peak (5273m) and N peak (ca. 5275m), descending to Tinkiqocha (ca. 4350m). It is possible that the peaks were climbed earlier, especially the SE peak.

Patrón Sudeste 5236m The most frequently climbed route is the SE slope either on hard, banded argillite or snow and ice, from Mina Raura. W. Jenks (solo) made the first recorded attempt on the rock route to nearly 5100m from Caballoqocha. It took him 3 days to approach on horseback from Goyallarisquisga to the east in June, 1939.

Patron Central ca. 5250m This peak is usually climbed as part of a traverse of the 3 summits facing the mine.

Patrón Noroeste 5273m This, the NW peak, is often climbed by the W face, after ascending the Torre de Cristal-Patrón col from the Mina Raura.

The above three peaks have been called Patrón Sur, Patrón Central and Patrón Norte, in some accounts, since these are the only three peaks seen from the mine area. However, the true geographical north peak (ca. 5275m), possibly the highest summit on the mountain, cannot be ignored, and is now designated Patrón Norte, and the others are designated as geographically as possible considering this history.

Patrón Norte ca. 5275m The route used on this peak is likely to have been the south ridge, though no conclusive proof has been found.

Nev. Torre de Cristal 5529m (Peak 10-5539m Miller-Hodgson map) Called Flor de Loto (Lotus Flower) from the east.

Route of first ascent unknown but probably from Mina Raura up the SE spur, or traverse on the eastern slopes below the crest of the spur; climb along the narrow, doubly-corniced E summit ridge.

S. Jungmeier, E. Krenmayr. 31 July, 1957.

RPA 3 1956/57

Route 1. As above but beginning on the NE slopes of Matapaloma, up loose steep rock to near the crest of the SE spur for a bivouac. Then proceed via the SE spur and E ridge of Torre de Cristal. The minor peak on the NE spur of Torre de Cristal was climbed on the descent.

NEVADOS CHIRAJANKA—ANTAKALLANKA REGION

A massif of isolated minor peaks to the north of and approached from Mina Raura.

NEVADOS SIETE CABALLEROS—SANTA ROSA— CONDORSENGA REGION

The eastern arm of the Cordillera Raura is almost always approached from Mina Raura or the mine road.

Nevs. Siete Caballeros ca. 4950–5100m (Seven Gentlemen). The Siete Caballeros have been ascended by many parties from Mina Raura. The southernmost peaks are probably most frequently climbed from the west, and it is probable that earlier ascents than those recorded, have been made.

N. Bedón, S. Jungmeier, E. Krenmayr climbed a number of the Siete Caballeros from Mina Raura, beginning on the northern glacier on 29 July, 1957. At that time they were called the Cinco Caballeros, at least in climbing journals. The peaks traversed would most likely have been:

4, 3, 3 Sur, 2, and 1 (see map).

RPA 3, 1957/58

The first traverse, probably from S to N is believed to have been made by E. Booth, and P. Bebbington, when they climbed 10 peaks on the ridges north of Santa Rosa in 6 days. 13–18 August, 1961.

In addition the American Alpine Journal; the Alpine Journal, London, England; the Journal of the Swiss Foundation for Alpine Research; and the Revista Peruana de Andinismo provide or used to provide summaries of climbing activities in Peru. Only one issue of Relieve was ever published, now out of print, as are back issues of the Revista Peruana de Andinismo.

Much of the needed route information could only be obtained by personal communication with the following people to whom I am greatly indebted; however any inaccuracies are my responsibility. Corrections and additions would be welcomed, especially those concerning the Austrian Expedition of 1957, the English Expedition of 1961, and climbs that have been inadvertently overlooked.
