Salar de Uyuni
The Bolivian Altiplano has a lot of beautiful lakes - some fresh,
some saline and very colorful, some dry.
The collection includes the largest salt flat in the world - Salar
de Uyuni, an expanse of white salt 10,582 sq. km in size.
It is dry for most of the year, but is covered by a this layer of
water during the rainy season (usually November-March).
The salar is located at 3653 m above the sea level, and
is estimated to contain 10 billion tons of salt. It takes
a few hours to
drive across Salar de Uyuni (or Salar de Tunupa) is the world's
largest salt flat at 10,582 square kilometers.
It is located in the Potosí and Oruro departments in
southwest Bolivia, near the crest of the Andes, and is elevated
3,656 meters above the mean sea level. The Salar was formed
as a result of transformations between several prehistoric
lakes.
It is covered by a few meters of salt crust, which has an
extraordinary flatness with the average altitude variations
within
one meter over the entire area of the Salar.
The crust serves as a source of salt and covers a pool of
brine, which is
exceptionally rich in lithium. It contains 50 to 70% of the
world's lithium reserves, which is in the process of being
extracted.

The large area, clear skies and exceptional surface flatness
make the Salar an ideal object for calibrating the altimeters
of the Earth observation satellites. The Salar serves as the
major transport route across the Bolivian Altiplano and is
a major breeding
ground for several species of pink flamingos.
Salar de Uyuni is also a climatological transitional zone,
for towering tropical cumulus congestus and cumulus
incus clouds that form in the eastern part of the massive
salt flat during summer, cannot permeate beyond the salt flat's
considerably more arid
western edges, near the Chilean border and the Atacama Desert.

Lithium is a soft, silver-white metal that belongs
to the alkali metal group of chemical elements. It is represented
by the symbol
Li, and it has the atomic number 3. Under standard conditions
it is the lightest metal and the least dense solid element.
Like all alkali metals, lithium is highly reactive and flammable.
For this reason, it is typically stored in mineral oil.
When cut open, lithium exhibits a metallic luster, but contact
with moist air corrodes the surface quickly to a dull silvery
gray,
then black tarnish. Because of its high reactivity, lithium
never occurs freely in nature, and instead, only appears in
compounds,
which are usually ionic.
Lithium occurs in a number of pegmatitic minerals, but due
to its solubility as an ion is present in ocean water and
is commonly
obtained from brines and clays. On a commercial scale, lithium
is isolated electrolytically from a mixture of lithium chloride
and
potassium chloride.
Lithium and its compounds have several industrial applications,
including heat-resistant glass and ceramics, high strength-to-
weight alloys used in aircraft, lithium batteries and lithium-ion
batteries. These uses consume more than half of lithium production.

There are islands on the salar, isolated mountains sticking out
through salt, like nunataks in the middle of a glacier.
The most scenic (and sometimes too touristy) island has a strange
name Isla de Los Pescadores (Fishermen's Island)!

When the salar is covered with water, three species of flamingo
use it for nesting.
The most common is Chilean flamingo,
found here in flocks of thousands.
The birds feed on single-cell algae that grow rapidly
|
When
the salar is dry, the flamingo flocks move elsewhere, but
flocks of varying size can usually be found at smaller lakes
nearby, especially at Salar de Coipasa to the north, a huge
salt flat that always has water in the center.

It is unusual to see any other wildlife on the salar itself , but
the shores and islands are full of interesting animals,
from tiny lizards to vicunas. Isla de Los Pescadores is inhabited
by lots of viscachas

Common species of Salar de Uyuni shores:

Lagidium is a genus of rodent in the family
Chinchillidae. It contains the following species:
Northern Viscacha, Lagidium peruanum
Southern Viscacha, Lagidium viscacia
Wolffsohn's Viscacha, Lagidium wolffsohni
Lagidium ahuacaense - a new species from Ecuador described in
June 2009.
Members of this species are medium to large-sized rodents which
also looks remarkably like a long-tailed rabbit.
Soft dense fur covers its body, from the tips of its elongate
fur covered ears, edged with a fringe of white fur to the end
of its long,
curled tail. Their tails are bushy and can range up to about
1/3 of the length of its body. The forelimbs are relatively
short, while the
contrastingly long and muscular hind-limbs enable it to run
and jump with ease. However, the number of digits on the hind
feet is
reduced to 4 (apparent in Chinchillas as well). The color of
its fur varies seasonally and with age, but generally the upper
parts are
grey to brown, with tints of cream and black, while the under-parts
are pale yellow or tan. However, contrary to the former
statement, it has been stated elsewhere that they have pale
yellow or grey upper parts, and a black tail tip. They weigh
up to 3 kg
and have fairly delicate incisors in which the enamal of the
incisors are not colored.
The Northern Viscacha, Lagidium peruanum,
occurs in the central and south Peru, and northern Chile. The
distribution is
shown to be the Andes mountain in Peru at elevations ranging
between 3,000 to 5,000 m Lagidium peruanum naturally
occurs
in Chile and Peru.
Lagidium peruanum prefers dry, rocky, habitats between
the timber line and snow line of the Andes mountains with sparse
vegetation and coarse grasses. It is an herbivorous species
and is found near water that offers better vegetation than the
drier regions within their habitats.
Lagidium peruanum are diurnal species that are active
throughout the year. They leap among rocks and performs a series
of
whistles and trills associated with warning. Colonial structures
are composed of small family units of two to five individuals
in a
subdivided colony that can be as large as 75 animals.

viscacha, Lagidium viscacia, - Overview

|
The Southern Viscacha, Lagidium viscacia,
occurs in southern Peru, southern and western Bolivia, northern
Chile and western
Argentina. They occur between 2,500 m to 5,100 m above sea level.
Lagodium viscacia inhabits rocky mountain areas as well
as rock outcrops in steppe habitat. They are restricted to sparsely
vegetated,
rocky habitats from 2,500 to 5,100 m above sea level. This herbivorous
species is specialized and restricted to rocky habitats
where it colonizes rock crevices and also associate themselves
with available habitat that is patchy.
In large, steeper portions of the cliffs were more heavily used
than less steep portions. Habitat use both on and away from
the cliffs appears to be driven by predator avoidance. They
can probably more easily escape terrestrial predators on a steep
slope. They rarely venture away from rocks which provide a means
for escape from both aerial and terrestrial predators.
Lagodium viscacia are also diurnal and are most active
near sunrise and sunset. They spend the day on perches, grooming
and summing themselves. They are adept at moving over rocky
surfaces and do not hibernate (unknown found information as
to why).
Little data has been found about Lagidium wolffsohni. |

The Vicuña, Vicugna vicugna, or vicugna
is one of two wild South American camelids, along with the guanaco,
which live in the
high alpine areas of the Andes. It is a relative of the llama,
and is now believed to share a wild ancestor with domesticated
alpacas,
which are raised for their fibre. Vicuñas produce small
amounts of extremely fine wool, which is very expensive because
the animal
can only be shorn every 3 years. When knitted together, the
product of the vicuña's fur is very soft and warm. It
is understood that
the Inca valued vicuñas for their wool, and that it was
against the law for any but royalty to wear vicuña garments.

Both under the rule of the Inca and today, vicuñas have
been protected by law. Before being declared endangered in 1974,
only
about 6,000 animals were left. Today, the vicuña population
has recovered to about 350,000, and while conservation
organizations have reduced its level of threat, they still call
for active conservation programs to protect population levels
from
poaching, habitat loss, and other threats.
The vicuña is the national animal of Peru; its emblem
is used on the Peruvian coat of arms representing the animal
kingdom.

The Vicuña is considered more delicate and graceful than
the Guanaco, and smaller. Its long, woolly coat is tawny brown
on the
back while the hair on the throat and chest is white and quite
long. The head is slightly shorter than the guanaco's and the
ears are
slightly longer. The length of head and body ranges from 1.45-1.60m;
shoulder height from 75 to 85 cm; weight from 35 to 65 kg
To prevent poaching, there is a round up every year, and all
vicuñas with fur longer than 2.5 cm are shorn.

Phrygilus is a genus of mainly Andean seed-eating
tanagers commonly known as sierra-finches.
Phrygilos means finch in
Ancient Greek. Sometimes classified in the bunting and American
sparrow family Emberizidae, more recent studies have
shown them to belong in the Thraupidae. The genus appears
to be polyphyletic consisting of at least three distinct lineages
which in future
may need to be split into separate genera.
Group 1 - The "Hooded" group.

Finally, a little more about SALT
There are a few springs breaking through the salt. Called "eyes"
(ojos del salar),
they are a major driving hazard during the rainy season.

People have been mining salt from the salar for centuries,
and 25,000 tons are now extracted annually. Piles of drying salt are
a common sight on the eastern side.
There are a few very old villages along the shores.
