- Main Entry: gla·cier
- Pronunciation: \ˈglā-shər also -zhər, especially British ˈgla-sē-ər or ˈglā-sē-\
- Function: noun
- Etymology: French, from Middle French dialect (Franco-Provençal), from glace ice, from Latin glacies; akin to Latin gelu frost — more at cold
- Date: 1744
: a large body of ice moving slowly down a slope or valley or spreading outward on a land surface
A glacier is a perennial mass of ice which moves over land. A glacier forms in locations where the mass accumulation of snow and ice exceeds ablation over many years. The word glacier comes from French via the Vulgar Latin glacia, and ultimately from Latin glacies meaning ice.[1]
Glacier ice is the largest reservoir of fresh water on Earth, and is second only to oceans as the largest reservoir of total water. Glaciers cover vast areas of the polar regions and are found in mountain ranges of every continent except Australia. In the tropics glaciers are restricted to the highest mountains. The processes and landforms caused by glaciers and related to them are referred to as glacial. The process of glacier growth and establishment is called glaciation. Glaciers are indicators of climate and are important to world water resources and sea level variation.
The distinctive blue tint of glacial ice is often wrongly attributed to Rayleigh scattering due to bubbles in the ice. The blue color is actually created for the same reason that water is blue, that is, its slight absorption of red light due to an overtone of the infrared OH stretching mode of the water molecule.[7]One day we cruised through Glacier Bay National Park - check it out here
and the next day we visited College Fjord Alaska check it out here.
College Fjord is named after renowned East Coast colleges.
The bottom four pictures are of the Mendenhall glacier (no it's not named after Bronco as Rick thought...) which is located just outside Juneau. All of these glaciers are MAGNIFICENT!!!
(Although we couldn't stop thinking about Jack and Rose, poor kids.)

Glaciers are awe-inspiring, beautiful, and very interesting. Thanks for the beautiful pictures, Vonnie. The pictures look terrific, and even better blown up to full size.
Evidence of the polar ice caps melting!!!!! I like the way the British say it. Very cool pics.
P.S. Fjord is a cool word. Reminds me of someone I know.
WOW!!!!
