22-638: The Huayhuash range is 30 km long north to south and includes seven peaks over 6000 m including Yerupajá , which, at 6,617 metres (21,709 ft), is the second highest peak in Peru. Another notable peak, Siula (6,344 m) was made famous by mountaineer Joe Simpson in his book Touching the Void . Compared to the neighboring Cordillera Blanca , Huayhuash possesses narrower valleys and higher mountain passes. There are many lesser peaks surrounding those covered by ice, and several passes exceeding 5,000 m. It

44-444: A capacity to thrive in disturbed or ecologically challenging environments. Its adaptability to infertile soils is attributed to its ability to establish both ectomycorrhizal and actinorhizal relationships. Recognized for its rapid growth, this species plays a pivotal role in enhancing soil fertility by augmenting soil organic matter, nitrogen levels, and cation-exchange capacity. Given the many advantages that A. acuminata offers,

66-425: A few successful ascents of the peak because it is one of the hardest Andean high peaks to climb. The most popular route is the southwest face. The approach is normally made from Huaraz southwards via Chiquián and Jahuacocha. Based on the elevation provided by the available Digital elevation models , SRTM2 (6558m with voids ), SRTM filled with ASTER (6551m with voids ), TanDEM-X (6110m with voids ), Yerupaja

88-489: A further benefit. The timber is light to mid reddish-brown and fine grained. It is used for building bridges and pilings, for making coffins, boxes, crates, furniture and plywood. It also makes a good firewood that burns steadily. Alnus acuminata has been used traditionally in Central and South American medicine to treat acute inflammation. To evaluate the effectiveness of the anti-inflammatory claims and ascertain whether

110-416: A group of Canadian and Peruvian climbers were held hostage for 12 hours after a failed assassination attempt on a group of military police. None of the climbers or police were hurt, though one Senderista was killed. In the late 1980s a party of European trekkers were robbed and ordered to return to Huaraz with the message that future intruders would be killed. The remains of a guerrilla camp can be seen near

132-409: A straight trunk up to 150 centimetres (60 in) thick. The bark has many yellowish lenticels . The leaves are simple, oval with toothed margins. The inflorescences are catkins , separate male and female flowers on the same tree. The male flowers are up to 12 cm (5 in) long and pendulous, while the smaller female flowers are green, erect and resemble a small cone . After wind fertilisation,

154-491: Is about 6635 meters above sea level. This altitude was considered due to the lack of topographic data or even handheld GPS data. The height of the nearest key col is 4592 meters , so its prominence is 2025 meters . Yerupaja is listed as range or area, based on the Dominance system and its dominance is 30.6%. Its parent peak is Huascaran Sur and the topographic isolation is 148.8 kilometers . This information

176-576: Is found at approximately 4,800 m). The nearest villages are Chiquián (3,400 m) and Cajatambo (3,375 m). Some mining takes place in the area, so to the north of the mountains there is an unsurfaced road leading up to as high as 4750 m. In 2002, the Peruvian Ministry of Agriculture declared the Huayhuash mountain range a "reserved zone" and prohibited certain economic activities, including any future mining. A selection of

198-462: Is necessary to travel a considerable distance from the central range to find ground lower than 3,000 m, even on valley floors, and the range is often taken to include this much larger area. The vegetated areas of the range are part of the Central Andean wet puna ecoregion . The area is scarcely populated, containing only small settlements generally found below 4000 m (the snowline

220-676: Is the second-highest in Peru and the highest in the Huayhuash mountain range. The summit is the highest point in the Amazon River watershed , and was first reached in 1950 by Jim Maxwell and Dave Harrah , and its northern peak (Yerupajá Norte) in 1968 by the Wellingtonian Roger Bates and Graeme Dingle . Many visitors consider Yerupajá to be the most spectacular peak in South America. There have been only

242-582: The area include: the giant conebill , the tit-like dacnis , the torrent duck , the Andean mountain cat , the taruca , the Andean condor , the peregrine falcon , the giant coot , etc. Yerupaj%C3%A1 Yerupajá is a mountain of the Huayhuash mountain range in west central Peru , part of the Andes . It is located at Áncash , Bolognesi Province , Lauricocha Province . At 6,635 metres (21,768 ft) (other sources: 6,617 m (21,709 ft)) it

264-427: The area is considered generally safe. Near the north shore of the lake Viconga, the remains of an old Shining Path base camp can be still visited, including a shooting range, barracks and a training field. The area preserves high elevation Andean grasslands and patches of forest. Some of the native tree species present in the area are the Andean alder and trees of the genus Polylepis . Animals that can be found in

286-458: The dry winter months of May to September, and the cities Huaraz and Caraz over 100 & 167 km away are the usual choice for organizing and hiring camping a/o logistical support. Chiquián was the "Gateway to the Huayhuash" for a long time. But nowadays, daily buses (locally called colectivos ) go deep into the mountains to the village Llamaq (3,300 m) and with private transport, as far as Cuartelwain camp, reached both by road built in

308-655: The female flowers develop into 2 cm (0.8 in) long dehiscent, woody brown fruits. There are 80 to 100 winged seeds per fruit, and these are liberated when ripe, leaving the dried out fruit husks on the tree. There are three subspecies: Alnus acuminata subsp. acuminata occurs from Colombia and Venezuela south to northern Argentina; Alnus acuminata subsp. arguta (Schltdl.) Furlow occurs from northwestern Mexico south to Panama; and Alnus acuminata subsp. glabrata (Fernald) Furlow occurs in central and southern Mexico. Alnus acuminata grows at altitudes between 1,500 and 3,200 metres (4,900 and 10,500 ft) in

330-587: The highest peaks of the Huayhuash range is listed below. The range has become noted for trekking in the form of the Huayhuash Circuit , which is considered a challenge trail and is undoubtedly far more demanding than the famous Inca Trail in the south of Peru. Fewer people trek the Cordillera Huayhuash than the nearby Cordillera Blanca . The full circuit is about 130 km long and generally takes between ten and fourteen days, depending on

352-524: The lake Viconga. Two foreign trekkers are known to have been murdered in Cajatambo in August 2002, though this is thought to have been motivated by robbery. In 2004, four hikers who resisted armed robbery were shot, one of which died of blood loss before they could be rescued. Since this last incident, the local communities began to charge a "protection" fee for passing in the private properties. Since then,

374-583: The late 90s and 2000s, becoming now the new trail heads for starting/ending. More challenging yet is the Alpine Circuit, which encircles the peaks at closer proximity. The Alpine Circuit involves some rock climbing and glacier travel, and takes 8–10 days to complete. There are several lakes like Solteracoha (or Solterococha), Siula, Jahuacocha, Carhuacocha and Sarapococha . The region is primarily composed of limestone, accompanied by sandstone and slate. These sedimentary rocks originated as deposits on

396-450: The mountain ranges in tropical Central and South America from Mexico to northern Argentina. It mostly grows on areas with 1000–3000 mm of rainfall, on slopes and valleys. It tolerates poor soils and acid conditions, but prefers silt or sandy silt soils. It is a fast-growing tree, a pioneer species used for watershed protection and can be used for soil improvement because it has root nodules that fix nitrogen. A. acuminata demonstrates

418-465: The ocean floor and were subsequently uplifted and folded due to tectonic plate convergence. Over time, these rocks have eroded and developed cracks. Marine fossils, such as bivalves and ammonites , can occasionally be found embedded in the rock. Until the group's effective defeat in 1992, the Huayhuash range was used as a remote base by the Shining Path communist guerrilla. On July 28, 1988,

440-401: The species has gained popularity in agroforestry. Farmers with an average of 130–161 Alnus trees per hectare found benefits in their contributions to carbon sequestration, a reduction of soil erosion and increased soil fertility according to a study done in northwest Rwanda. Providing resources needed for daily living in the region, such as firewood, lumber, and stakes for climbing bean trees, is

462-420: The variant taken. Most of the walking and most of the campsites are above the 4,000 m tree line , so the landscape appears rugged and mountainous, affording views over very wide areas. The area is noted for its spectacular glacial lakes. Hot springs can also be found in the area, at Viconga Campsite precisely. Condors , llamas , alpacas and viscachas can be seen. Trekking is almost always undertaken in
