| Stretching
over 90 miles from the core of the 12-million acre Wrangell-St. Elias National
Park to the head of Yakutat Bay, the mighty Hubbard Glacier is one of Alaska's
largest and most unpredictable. Hubbard Glacier is only one of the hundreds
of glaciers that have survived from the last mini-iceage. Worldwide glacial
statistics are amazing; 10 percent of our world's total area is covered
with ice (up to two miles thick in some regions), equaling the percent
of land currently being used for agriculture. Glacier and polar ice store
more water than all the world's lakes, rivers, and the atmosphere combined,
and if the world's ice caps melted completely, sea levels would rise enough
to flood much of the Earth and more than half of the world's cities. |
