/font>Irish
team completes the Sixth of Seven
Pat and Clare have side tracked to Australia and today, Tuesday November 29th,
climbed the sixth mountain, Mt Kosciuszko, in their Seven Summits challenge.
Although it was cold, wet, windy and sleeting, it was a relaxing summit before
the ordeal of Antarctica.
Statement from Australia (Pat and Clare)
"We are delighted to be approaching the final stage of this challenge.
It has been an amazing journey as Irish adventurers and now that we have completed
Kosciuszko in Australia, we are very excited about the expedition in Antarctica.
We have no doubt that this expedition will be demanding, but we believe that
as an Irish team, we will succeed in completing our challenge of climbing Mt
Vinson."
Clare and Pat head for Punta Arenas in Chile on tomorrow 30th November, where
they will be met their team mate, John Dowd, from Waterville County Kerry, on
December 2nd. The team then depart to the Antarctic Continent by plane where
they will have some time to prepare their gear before flying out once again this
time to a glacier located within reach of Mt. Vinson.

Irish
Seven Summits Expedition heads to 80 degrees South, Antarctica
Dr Clare O'Leary and Pat Falvey headed south to Australia on the 23rd of November
to bag Kosciuszko (2228m) the 6th and smallest of the peaks on the final leg
of their challenge. They then fly via New Zealand to Chile before embarking on
what is without doubt the coldest of all of the continental high points in the
heart of one of the most remote places in the world.

Final checks on communication gear
Mt. Vinson (4897m) in the Ellsworth mountain range situated 600 miles from the
South Pole is the finale of the challenge. If successful Dr Clare O Leary’s
will become the first Irish Female to complete the Seven Summits, of which only
14 other women world wide has completed. Pat, who is the only Irish person to
have completed the challenge, if also successful will have completed it twice,
of which only a hand full of people worldwide have so far achieved. John Dowd
will meet up with the team in Punta Arenas, Chile their departure point for the
Antarctic. This will be John’s second continental high point, having summited
McKinley in June.
Before they departed Dr Clare O'Leary commented…
‘ I can hardly believe that we are starting out on the final leg of
the seven summits. I think Mt Vinson (in Antarctica) will be one of the most
amazing climbs of the seven and can't wait to see this spectacular continent.
I guess at this stage I'm feeling excited more than anything.’
More dispatches will be posted on their progress soon

Objectives
• First Irish female to complete the seven
summits
• First Irish person to complete the seven summits twice
(Pat Falvey completed his first seven summit challenge
in 1997)
Climbing the Seven Summits
About 110 mountaineers have climbed all 'Seven Summits' - the highest peak
on each of the seven continents. The first was Dick Bass, an American businessman,
on April 30, 1985.
Asia - Mt. Everest, Tibet-Nepal - 29,035ft/8,850m
South America - Mt. Aconcagua, Argentina - 22,834ft/6,960m
North America - Mt. McKinley (Denali), United States, Alaska - 20,320ft/6,194m
Africa - Mt. Kilimanjaro, Tanzania - 19,340ft/5,995m
Europe - Elbrus, Russia/Georgia - 18,510ft/5,642m
Antarctica - Vinson Massif, Ellsworth Mts. - 16,066ft/4,897m
Australia - Kosciusko, Australia - 7,310ft/2,228m
Some climbers believe that the true Seven Summits should include Carstensz
Pyramid (16,023 ft.) in Irian Jaya, Indonesia, rather than Australia's Kosciusko.
Carstensz is the highest summit in Australia/Oceania, but strictly speaking,
Oceania is not a continent.
The Continents
A continent is defined as a large unbroken land mass completely surrounded
by water, although in some cases continents are (or were in part) connected
by land bridges. The seven continents are North America, South America, Europe,
Asia, Africa, Australia, and Antarctica. The island groups in the Pacific are
often called Oceania but this name does not imply that scientists consider
them the remains of a continent.
Political considerations have often overridden geographical
facts when it came to naming continents. Geographically,
Europe, including the British Isles,
is a large western peninsula of the continent of Asia; and many geographers,
when referring to Europe and Asia, speak of the Eurasian continent. But traditionally,
Europe is counted as a separate continent, with
the Ural and the Caucasus
mountains forming the line of demarcation between
Europe and Asia. To the south of Europe,
Asia has an odd-shaped peninsula jutting westward, which has a large number
of political subdivisions. The northern section is taken up by Turkey; to
the south of Turkey there are Syria, Iraq, Israel,
Jordan, Saudi Arabia, and a
number of smaller Arab countries. All these are part of Asia. Traditionally,
the island of Cyprus in the Mediterranean is also considered to be part of
Asia. The Caribbean islands, Central America, and Greenland are considered
part of North America.
Continental Drift and Plate-Tectonics Theory
Source: U.S. Dept. of the Interior, Geological Survey
According to the theory of continental drift, the world was made up of a
single continent through most of geologic time. That continent eventually
separated
and drifted apart, forming into the seven continents we have today. The first
comprehensive theory of continental drift was suggested by the German meteorologist
Alfred Wegener in 1912. The hypothesis asserts that the continents consist
of lighter rocks that rest on heavier crustal materialósimilar to the
manner in which icebergs float on water. Wegener contended that the relative
positions of the continents are not rigidly fixed but are slowly movingóat
a rate of about one yard per century.
According to the generally accepted plate-tectonics theory, scientists believe
that Earth's surface is broken into a number of shifting slabs or plates,
which average about 50 miles in thickness. These plates move relative to
one another
above a hotter, deeper, more mobile zone at average rates as great as a few
inches per year. Most of the world's active volcanoes are located along or
near the boundaries between shifting plates and are called plate-boundary
volcanoes.
The peripheral areas of the Pacific Ocean Basin, containing the boundaries
of several plates, are dotted with many active volcanoes that form the so-called
Ring of Fire. The Ring provides excellent examples of plate-boundary volcanoes,
including Mount St. Helens.
However, some active volcanoes are not associated with plate boundaries,
and many of these so-called intra-plate volcanoes form roughly linear chains
in
the interior of some oceanic plates. The Hawaiian Islands provide perhaps
the best example of an intra-plate volcanic chain, developed by the northwest-moving
Pacific plate passing over an inferred 'hot spot' that initiates
the magma-generation and volcano-formation process.
