The Land
The
country is washed on the north and west by the Atlantic Ocean
and on the east by the North Sea. Its breadth varies from 154
miles to as little as 26 miles. The country has 2,300 miles of
coastline, an incredible length for the size of the mainland.
Scotland is indeed a land of contrasts, from the austere majesty
of the mountains to the subtle undulations of the Lowland valleys,
and from the dramatic cliffs to the dense forests. The country
also boasts 787 major islands; almost all lying off the northern
or western coasts. Picturesque lochs and rivers are scattered
throughout the whole country.
The
country is a Geologists playground, with rocks displaying 3 billion
years of geological time. Starting with hard granite in the Western
Isles, which was formed before life itself developed on earth,
the rocks tell a long story of lava flows, eras of mountain-building,
numerous ice ages and even a time when the land was briefly separated
from England.
Four
major fault and thrust lines, running across Scotland from northeast
to southwest, define the main geological zones. The U-shaped valleys
in the Highlands are a legacy of the last Ice Age. The weight
and movements of glaciers broke off spurs, deepening and rounding
out the existing river valleys. The Basalt Columns of the Isle
Of Staffa were formed 60 million years ago as a flow of lava cooled
slowly, contracting and fracturing in a distinctive hexagonal
pattern similar to the Giant's Causeway in Ireland. The Devonian
Sandstone in the Orkney Islands has eroded the horizontally layered
rock into spectacular cliffs and stacks, as with the Old Man Of
Hoy.
