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.

Famous quotes containing the word topography:
“That the mere matter of a poem, for instance—its subject, its given incidents or situation; that the mere matter of a picture—the actual circumstances of an event, the actual topography of a landscape—should be nothing without the form, the spirit of the handling, that this form, this mode of handling, should become an end in itself, should penetrate every part of the matter;Mthis is what all art constantly strives after, and achieves in different degrees.”
—Walter Pater (1839–1894)
