Pico da Neblina (Portuguese pronunciation: [ˈpiku dɐ neˈblĩnɐ], Mist Peak) is the highest mountain in Brazil, 2,994 metres (9,823 ft) above sea level, in the Serra da Neblina, Serra do Imeri, a section of the Guiana Highlands on the Brazil–Venezuela border. As determined by a border survey expedition in 1962, its summit lies just within Brazilian territory, at a horizontal distance of only 687 m (2,254 ft) from the Venezuelan border at Pico 31 de Março.
Officially, Pico da Neblina is located in the municipality of Santa Isabel do Rio Negro, state of Amazonas. However, this is of next to no practical significance, since the mountain is inaccessible from the urban seat of the municipality, about 180 km (112 mi) away, and federal authority over the national park, the Yanomami reservation and the border security area supersedes municipal authority in all practical respects. The nearest city is actually São Gabriel da Cachoeira, about 140 km (87 mi) in a straight line, from where virtually all climbing expeditions depart.
The mountain is contained in the Brazilian Pico da Neblina National Park; its northern slopes are also protected in Venezuela's Serranía de la Neblina National Park. The twin parks, together with the neighbouring Parima Tapirapecó National Park (Venezuela), form a protected area complex of about 80,000 km², possibly the largest national park system in tropical rainforests in the world. Pico da Neblina is also located within the territory of the Yanomami people's reservation.
Pico da Neblina is often mentioned as being on the exact border between Brazil and Venezuela. This is true for its massif as a whole, but the main summit is wholly in Brazil, 687 metres from the actual border. It is also sometimes mentioned as being the highest point in South America outside of the Andes, but this is not correct either: the title belongs to Sierra Nevada de Santa Marta in Colombia, which is almost twice the height of Pico da Neblina and completely detached from the Andes. However, Pico da Neblina is indeed the highest point east of the Andes range, and therefore of a large portion of the continent. Neighbouring Pico 31 de Março, which is on the precise international border, is also the highest point in Venezuela outside of the Andes.
For 39 years, based on an uncontested measurement performed in 1965 by topographer José Ambrósio de Miranda Pombo, using a theodolite, the elevation of Pico da Neblina was thought to be 3,014 metres (9,888 ft), but a much more accurate measurement performed in 2004 with state-of-the-art GPS equipment by cartographer Marco Aurélio de Almeida Lima, a member of a Brazilian army expedition, puts it at 2,994 m (9,823 ft). This is now recognised by the Brazilian Institute of Geography and Statistics (IBGE), the federal government's official geographic survey and census agency, which jointly organised the expedition.
Geology and topography
The Neblina Massif is a glaciated tor composed of a tilted block of sandstone overlying Precambrian metamorphic rocks. The peak is an impressive sharp rock pyramid or tooth, towering high (when the peak is visible) over the nearby lowlands on the Brazilian side, as the Imeri range quickly rises from only about 100 metres above sea level to about 2,000 metres at the base of the peak in just a few kilometres; from there the peak rises sharply.
The Venezuelan side of the massif is hillier and the altitude gradient to the northern plains is less abrupt, although deep chasms and high walls still exist. Neighbouring Pico 31 de Março can be considered a secondary summit of Pico da Neblina; it has a smoother, rounder shape and is sometimes difficult to be clearly distinguished from Pico da Neblina on photographs, depending on angle and distance. Due to Pico da Neblina's equatorial latitude, while it can be cold on top, sub-freezing temperatures and frost appear to be rare (no permanent measurements are undertaken), and there is no snow.
There is little documentation available today on the peak's discovery, and virtually none of it is authoritative, even though Brazilians only discovered the mountain fairly recently, in the mid-20th century. This late discovery can be understood if one remembers how extremely remote, inaccessible and uninhabited that part of the Amazon region is even today, and that it could hardly be expected that such a high mountain (by Brazilian standards) could be found standing next to the vast, low-lying Amazon Basin, even though it was known that there were mountains in that area. Moreover, as its own name states, Pico da Neblina is clouded and hidden from view most of the time.
All this led to it only being discovered in the 1950s. The exact date and circumstances are obscure and not documented, but a popular story often heard in Brazil says that it was supposedly seen and reported by an airline pilot who overflew it at a luckily cloudless moment. However, the massif was known well before that on the Venezuelan side, where it was called Cerro Jimé. In 1954, eight years before the Pico da Neblina was successfully climbed, the area was visited from the north by an expedition led by botanist Bassett Maguire, who reached the northern summit plateau of the massif and observed the highest peak, then unnamed, estimating it to be between "8,000-9,000 feet." The whole massif was named Cerro de la Neblina, since Maguire and Reynolds considered at the time that the massif constituted a separate formation from the Imeri range to the southeast.
Soon after the expedition, the highest peak, although unclimbed, was named Pico Phelps in honour of eminent ornitologist William H. Phelps, Jr. At that time, the peak was thought to lie entirely within Venezuelan territory. During the 1962 Brazilian expedition, it was determined that the highest summit lies entirely in Brazil. The Brazilian expedition renamed the summit peak to Pico da Neblina, causing some confusion with the name Cerro de la Neblina, which is used in Venezuela to refer to the whole massif. The subsidiary summit on the Venezuelan-Brazilian border was named Pico 31 de Março in Brazil, but it is now known as Pico Phelps in Venezuela.
In the 1950s, it was not yet clear whether Pico da Neblina was in Brazilian or Venezuelan territory, and its precise elevation was not yet known. Therefore, it was still widely held for many years after the peak's discovery that Brazil's highest mountain was Pico da Bandeira (2,892 m or 9,488 ft), between the southeastern states of Minas Gerais and Espírito Santo, in a much more populated, developed and easily accessible region. Only in 1965 it was found and became widely known that Pico da Neblina was the country's highest mountain. Pico da Bandeira remains the highest Brazilian mountain outside of the Amazon region, and the third highest overall, after Pico da Neblina and 31 de Março.
Due to its location in a national park in a border area that is also part of Yanomami territory, access to the area is restricted and depends on a special permit by the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA). The permit can be obtained at IBAMA's office in São Gabriel da Cachoeira, but all climbers must take an accredited local guide. A four-day trek each way should be expected, three of which consisting of a jungle trek in the rainforest that can be as hard and challenging as the climb itself. Rescue is close to impossible in the area.
Onchocerciasis or "river blindness," a parasitic disease that can cause permanent blindness and is transmitted by a black fly, is endemic in the area, albeit with a low incidence; malaria and yellow fever transmission are also possible. Therefore, climbers are advised not only to take the utmost precaution in avoiding insect bites, but also to discuss preventive and/or therapeutic strategies with qualified physicians who are familiar with tropical diseases.
Robson Czaban, a Brazilian photographer who climbed Pico da Neblina in 1998, reports on his adventure account (in Portuguese) that there are always some gold panners on a small plateau just below the peak, at about 2,000 m (6,100 ft), called Garimpo do Tucano, which serves as the base camp for the last and steepest part of the climb. While the panners' presence there is technically illegal, they are widely tolerated by Brazilian authorities, and Czaban speculates that this would be because in such a remote area, they are believed to watch the border and nature better than IBAMA's rangers and the army would have the means to do. Czaban reports them to be very friendly and helpful.
