For years, Pico das Agulhas Negras was thought to be the highest mountain in Brazil.
The title later went to Pico da Bandeira, in the Caparaó range between the states of Minas Gerais and Espírito Santo (now known to be at 2,891 metres (9,485 ft)).
In 1965, it was found that Pico da Neblina, in the state of Amazonas, was, in fact, the highest, with a currently revised height of 2,995 metres (9,826 ft).

Even then, Pico das Agulhas Negras was still thought to be the highest point in the Mantiqueira Mountains, until a 2001 GPS measurement (later confirmed by an official joint expedition of the Brazilian Army and the Brazilian Institute for Geography and Statistics - IBGE) showed that nearby Pedra da Mina was that mountain range's highest point at 2,798 metres (9,180 ft), about seven metres higher than Agulhas Negras.
Pedra da Mina was higher even though Agulhas Negras was also found to be slightly higher than previously thought, at 2,791.55 metres (9,158.6 ft), rather than its previous official altitude of 2,787 metres (9,144 ft).
Pico das Agulhas Negras remains the highest point in Rio de Janeiro state.

In 2015, IBGE completed a new and more accurate mapping of the Brazilian territory regarding the geoid, the irregular imaginary surface based on the Earth's gravitational field that is the reference for altitude measurements.
This led the institution to recalculate the altitude of the mountains measured in the earlier project, according to the new reference.
The new data were published in February 2016.
Pico das Agulhas Negras was then found to stand at 2,790.94 metres (9,156.6 ft), a difference of 61 cm or about two feet.
