Cerro Neblina vs Pico da Neblina
editCurrently "Cerro Neblina" redirects to "Pico da Neblina". This is somewhat inaccurate. I'll explain. The whole of the Neblina Massif is known in Venezuela as "Cerro Neblina" or "Serrania de La Neblina", while in Brasil, the massif is considered as part of, and referred to as, "Serra do Imeri". Brasilians refer to the highest point as "Pico da Neblina", while in Venezuela the name refers to the whole mountain. I think this should be clarified. A different page describing the whole massif is in order. For example, the description of Basset Maguire's expedition to the mountain would be much better described there (he arrived before the Phelps and led the climbing assault, etc.). — Preceding unsigned comment added by Dycotiles (talk • contribs) 14:54, 6 November 2011 (UTC)
Pico da Neblina Height
editThe information on elevation of Pico da Neblina in this article (2.994 m) conflicts with the same information in the List of Mountais in Brazil, that states 3.014 m.
- See revised text indicating the correct from 3,014 to 2,994. --Bejnar 17:55, 3 October 2007 (UTC)

The 3,014-m figure came from a primitive measurement (for today's standards) made in the early 1960s with a theodolite. It was accepted for about 40 years, because the peak is extremely remote and almost inaccessible (not to mention cloudy most of the time, as its own name states), making a new measurement hardly feasible during most of that period. Apparently, it also never occurred to anyone that the figure might have been imprecise.
In 2001, however, the Brazilian Institute for Geography and Statistics (IBGE) and the Brazilian Army's Military Engineering Institute (IME) decided to undertake a more precise measurement of the country's highest mountains. New technologies (namely GPS) had appeared, air traffic had grown a lot in the previous decades, meaning more potential terrain collision risks, and other countries were also performing new measurements of their mountains.
After the usual red tape, wait for funding and a lengthy preparation, the so-called "Highest Points Project" (Projeto Pontos Culminantes, in Portuguese) was carried out in 2004-2005 by means of a series of expeditions by a special unit of the Brazilian Army, using high-precision, state-of-the-art GPS equipment. It was then found that Pico da Neblina was 20 meters lower than it was previously believed.
So, the 2,994-m figure for Pico da Neblina is as correct and accurate as it can be. As for the List of mountains in Brazil, I am editing it now to reflect the Highest Points Project's official data and correct a few other errors I found there.
