The Naukluft massif, which is
one of Namibia’s distinctive geological features, forms
a very prominent part of the escarpment. The mountain lies
at the edge of the Namib Desert, 16º E and 24º S,
just south of the Tropic of Capricorn.
The massif has an elliptical shape and constitutes a nappe
complex of predominantly deeply incised limestone and dolomite
rocks. It forms a plateau, which lies on the surrounding steppe
like a flat slab with steep sidewalls. The Naukluft Mountains
cover an area of around 2,100 km². They are 73 km in
length, with a width of 27 km. No other mountain range in
Namibia compares with the Naukluft’s morphological variety.
The actual mountain itself is made up of ancient pre-Cambrian
rock, being up to a billion years in age. The nappe complex
is predominantly comprised of carbonate rocks. Typical for
these rocks are inherent high porosity and karst solution
features.

Through this dissolution, an
extended porous network of underground pathways for the water
has been formed. Any rain that falls on the plateau is absorbed
into the rock and only reappears at the sides of the mountain
range or in the gorges (Dunja Gaedecke & Judith Kaperski,
2004, Die natürlichen Grundwasser-austritte in der Naukluft
und ihre Umgebung / “The natural groundwater seeps in
the Naukluft and its surroundings”, Technical University,
Braunschweig). This phenomenon can be observed easily during
a walk through the Quiver Tree Gorge. The high water retention
makes the Naukluft mountain plateau a natural water reservoir,
which borders the desert. Even in drought periods these perennial
springs are a boon to the area.

About 300 million years ago,
during the permocarbon glaciation period, a great transverse
gorge was carved through the Naukluft. The narrow gorge of
the Tsondab River, which runs from BüllsPort via Blässkranz
to Ababis, dissects the mountains into two massive parts.
During the rainy season, this river channels large amounts
of water from the more humid eastern portion to the arid parts
in the west. The water eventually disappears into the red
dune sands of the Tsondab Vlei.
The topographic and geological mapping of the area dates
back to 1935 when the German geologists Hermann Korn and Henno
Martin, spurred on by their mentors Heinrich Lotz and Hans
Cloos, started a survey of the area.
The mountain fauna are diverse and species-rich, and can
easily be observed at the multitude of springs. Birdlife in
the Naukluft is particularly spectacular.
