A Dinosaur of Rock
The
prospect from seaward has been likened to the half-submerged skeleton of a huge
dinosaur. Shetland is formed by the sunken stumps of ancient mountains which,
long before the dinosaurs, stood as high as the Himalayas.
Aeons
of erosion and repeated glaciations have gouged long ridges of hills and
valleys.
When the sea rose 120 metres after the ice age it created an
extraordinarily indented coastline.
Nowhere
is more than three miles from the sea and the landscape is studded with
thousands of fresh water lochs.
From five miles up, on jets flying between Scandinavia and the
west coast of North America, passengers see the islands as a delicate fretwork
of rock, heather and water, like a giant's jigsaw puzzle thrown down in a
tantrum.
