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.
