Hoodoos are
found mainly in the desert in dry, hot areas. In common usage, the difference
between hoodoos and pinnacles or spires is that hoodoos have a variable
thickness often described as having a "totem pole-shaped body." A spire, on the other hand, has a
smoother profile or uniform thickness that tapers from the ground upward. An
example of a single spire, as an earth pyramid, is found at Aultderg Burn, near Fochabers, Scotland.
Hoodoos range
in size from that of an average human to
heights exceeding a 10-story building. Hoodoo shapes are affected by the
erosional patterns of alternating hard and softer rock layers. Minerals deposited
within different rock types cause hoodoos to have different colors throughout
their height.
Hoodoos are
commonly found in the High Plateaus region of the Colorado Plateau and
in theBadlands regions
of the Northern Great Plains (both in North America). While hoodoos are scattered throughout these areas,
nowhere in the world are they as abundant as in the northern section of Bryce Canyon National Park,
located in the U.S. state of Utah (seegeology of the Bryce Canyon area).
Hoodoos are
a tourist attraction in the Cappadocia region
of Turkey where houses have been carved from
these formations. These rock formations were depicted on the reverse of the Turkish 50 new lira banknote
of 2005–2009. In French, they are called demoiselles
coiffées ("ladies with
hairdos") and a number of them are found in the Alpes-de-Haute-Provence;
one of the best-known examples is the formation called Demoiselles Coiffées de Pontis.
Đavolja
Varoš (Devil's Town) hoodoos in Serbia feature 202 exotic formations
described as earth pyramids or "towers", as the locals refer to them.
Since 1959, Đavolja Varoš has been protected by the state, and it is also a
nominee in the New Seven Wonders of Nature campaign.
The hoodoo
stones on the northern coast of Taiwan are unusual for their coastal setting.
The stones formed as the seabed rose rapidly out of the ocean during the Miocene epoch. Efforts have been made to slow the
erosion in the case of iconic specimens in Wanli.
The hoodoos
found in the Drumheller area of Alberta, Canada's badlands are a distinctive
feature which continue to attract thousands of visitors each year. These
hoodoos in particular formed between 70 and 75 million years ago during the Cretaceous
Period as clay and sand sediments from the Horseshoe Canyon Formation were
deposited. These hoodoos are able to maintain a unique mushroom-like appearance
as the underlying base erodes at a faster rate compared to the capstones, a
rate of nearly one centimeter per year, faster than most geologic structures.
