IN PREPARATION
Fjords or fiords, are the result of glacial action that has scoured out river valleys down to and even below sea level. It may have been as a result of the ice sheets that periodically covered the polar areas of the earth or it may have been due to mountain glaciers that are born in sizable snow fields at higher and cooler elevations. Glaciers that currently extend to the ocean are called tidewater glaciers. In some parts of the world, Norway is an example, tidewater glaciers no longer exist. For many, this is a sign that the earth's atmosphere is still in the heating stage of its cyclic pattern of heating and cooling that has persisted for millions of years.
Characteristically, the fiord exhibits a U-shaped valley with steep sides that are marked by abrupt ends of hanging valleys with many associated waterfalls. With the subsequent rise in sea level, or in some instances the drop of portions of the coastline, the valleys in their lower ends were flooded producing picturesque incursions of deep water far inland. An excellent example is the Sognefjord, the world's longest fiord of some 115 miles in length and 4,000ft deep, that has quite a number of feeder fiords through much of central southwestern Norway. The entire western coast of Norway is fiorded as is southeastern Alaska and British Columbia, Labrador and Greenland, Iceland, Scotland, southernmost Chile, Antarctica and the South Island of New Zealand. All these marine locations have moist air predominantly blowing onshore that are forced to rise over upland land masses that cool the air sufficiently for snowfalls of considerable amounts to accrue. This snowfall eventually collects in snow fields that produce the glaciers that inexorably move downhill by gravity to drastically erode the lower valleys and facilitate estuary. incursion.
