Title: Earth

Antelope Canyon
Located on the Navajo Indian Reservation in
Northern Arizona is one of the most unique
formations known as a slot canyon. It is
characterized by high and narrow sandstone walls
sometimes separated by only a few feet. The
Upper and Lower Antelope Canyon are formed by the
intense forces of flash floods that over time
have carved the walls into beautiful swirling and
colorful psychedelic patterns and passageways.
On a sunny day around noon light peeks through
the narrow crevices at the top of the canyon,
streams through the dusty air, resulting in
glorious columns of light that selectively
illuminates the sandy canyon floor. Unexpected
flash floods are a real danger when entering a
slot canyon .Clear skies in the canyon area does
not mean a flash flood cannot occur. Unforeseen
rainfall at higher elevations can and do result
in unexpected torrents of water hence the term
flash flood. DO NOT ENTER A SLOT CANYON IF
THERE IS ANY DANGER OF A FLASH FLOOD.
You could drown or worse yet get swept all
the way to Mexico !

Antelope Canyon Advisory
DO NOT ENTER A SLOT CANYON IF THERE IS ANY THREAT
OF NEARBY THUNDERSTORMS. There is always the
danger of flash floods upon entering a slot
canyonbe aware of not only the local weather
conditions but also surrounding areas located at
a higher elevations.
The extended photography tour of the upper
canyon, where your guide will verse you in the
geology of the canyon and offer photography tips
on a 15 minute walk through is a must see. In
the past you were then left alone in the canyon
to hike, explore, and photograph the convoluted
formations of the upper canyon The section you
get to explore is approximately one quarter mile
in length, but it is jam-packed with spectacular
scenery!  Blowing sand can also be a problem in
the canyon, so protect your camera from the
waterfalls of sand that often flow down from
the openings above when its windy. Update The
Navajo have set new rules for the 2003 season and
beyondall photographers are allotted a maximum
of two hours in the upper canyon.
END
If extended time is required inside the Canyon,
you must go through the Navajo Film Commission
for permits. In addition, you are now required to
have an authorized guide present at all times
while inside after some major abuses were
reported the previous summer.
