Devil's Tower
During an expedition in 1875 the
interpreter for Richard Irving Dodge
incorrectly translated the name of
the geological formation as being
"Bad God's Tower."   The name was
ultimately shortened to "Devil's
Tower" which it is still called today as
a result of the faulty translation.

Devil's tower is an igneous intrusion
of phonolite porphyry which is similar
in composition to granite but lacks
quartz.  Geologists are not in
agreement with respect to how
Devil's Tower formed.  However,
many geologists believe that it is
what remains of the volcanic plug or
the neck of a long extinct explosive
volcano.
Devil's Tower
Many Indian tribes consider Devil's
Tower to be a sacred place and call it
"Mato Tipila" meaning Bear Lodge.

Devil's Tower was used in the 1977
movie
Close Encounters of the Third
Kind
as a unique backdrop for filming.
This photograph was taken from along Wyoming Route 24 a few miles south
of the monument.
