In Turkish the name literally means Cotton Castle and it is easy to see
why it was given that name. Yet this geological wonder is also the site
of the ancient city of Hierapolis and over the centuries the two have
seemed to come together, almost merged into one. In fact some of the old
tombs in the city's necropolis have become part of landscape. The site
itself is a series of travertines and hot springs. The travertines here
have a concentric appearance and are almost sheer white giving the area
an ethereal appearance. The hot springs precipitate calcium carbonate at
their mouths and produce the strange almost organic looking structures.

Ice Towers of Mount Erebus (Antarctica)
Mt. Erebus is one of the largest active volcanoes on Earth. It reaches
nearly 4 km above sea level, and is renowned in volcanological circles
for its persistently active lava lake, which is sited in the summit
crater. The hot volcanic gas steaming from Erebus does more than fuel
for the lava lake. Hot gasses traveling up through cracks and fractures
in the volcanic rocks surrounding the Erebus summit have created an
intricate system of ice caves all over the mountain.

Fly Geyser (Nevada, US)
These look as if they were taken on another planet, or at least on the
set of a new and very expensive science fiction movie. Yet these
pictures are of the Fly Geyser which is very much of planet earth
(Nevada, US to be exact). The geyser can be found in Hualapai Valley
near Gerlach. It is a little seen phenomenon as the land upon which it
sits is private. It can be seen from State Road 34 but unless you have
permission the view from a distance is all you should attempt. Back in
1916 the owners of the place were looking for water in the hope of
creating rich farmland in this desert area of the state. They came
across water, yes, and the well worked for decades. However, the drill
that was driven down a shaft hit a geothermal pocket of water and the
result was a geyser.

Kasha Katuwe Tent Rocks (New Mexico, US)
New Mexico's Kasha-Katuwe Tent Rocks National Monument, where erosion
chisels rock formations formed by explosive volcanic eruptions between
six and seven million years ago. While the formations are uniform in
shape, they vary in height from a few feet to 90 feet throughout the
4,000 acre monument.

The Valley of the Moon (Argentina)
Ischigualasto, meaning “the place where you put the moon” is a remote
valley in Argentina. It is studded with geological formations left by
wind erosion, amazing standing stones and boulders that are so rounded
they look like enormous marbles. The valley's once-fertile ground is now
arid and contains so many plant and animal fossils that paleontologists
come from all over the world to study them.
Erosion over the
millennia unearths the fossils as well as other geological formations
such as a host of almost spherical concretions. The wind, inexorable and
patient, has pounded the local bedrock for an age. Revealed, the
boulders that mudstone – in its original wet form, helped to form look
as if giants have been playing marbles.

Danxia Landform (China)
This unique geological phenomenon, known as a 'Danxia Landform', can be
seen in several places in China. This example is located in Zhangye,
Gansu Province. Danxia, which means "rosy cloud", is a special landform
formed from reddish sandstone that has been eroded over time into a
series of mountains surrounded by curvaceous cliffs and many unusual
rock formations.

Enchanted Well - Chapada Diamantina National Park (Brazil)
Poço Encantado, or Enchanted Well, is located in the Chapada Diamantina
National Park in Bahia state, approximately 400 kilometres inland from
Salvador, the capital city of Bahia. This giant sunken pool is 120 feet
deep and the water is so transparent the rocks and ancient tree trunks
are visible on the bottom. When the sun is just right, light comes
through a crevice and creates a blue reflection on the water. Access to
this pond is highly controlled for environmental protection of its rare
and delicate ecosystem.

The Stone Forest (China)
The Shilin (Chinese for stone forest) is an impressive example of karst
topography. Its rocks are made of limestone and are formed by water
percolating the ground's surface and eroding away everything but the
pillars. It's known since the Ming Dynasty as the 'First Wonder of the
World.'

Wulingyan, Hunan (China)
The Hunan region is full of dramatic landscapes and the magnificent
Wulingyan is one of their biggest attractions. This geological wonder is
made up of over 3000 limestone karsts. There are scenic waterfalls and
some of Asia's biggest limestone caves.
Salar de Uyuni (Bolivia)
The Salar is one of the iconic images of Bolivia, a massive salt desert
in the middle of the Altiplano. It is an expansive, virtually flat
desert that reflects the sun in such a way as to create a mirror effect
with the sky. There are several lakes in the desert with strange colours
from the mineral deposits in the region.
Some 40,000 years ago,
the area was part of Lake Minchin, a giant prehistoric lake. When the
lake dried, it left behind two modern lakes, Poopó Lake and Uru Uru
Lake, and two major salt deserts, Salar de Coipasa and the larger Uyuni.
Uyuni is roughly 25 times the size of the Bonneville Salt Flats in the
United States. It is estimated to contain 10 billion tons of salt, from
which less than 25,000 tons is extracted annually.
