Glaciers
Pakistan has more glaciers than any other land outside the North and
South Poles. Pakistan's glacial area covers some 13,680 sq.km which
represents an average of 13 per cent of mountain regions of the
upper Indus Basin. The Karakoram of Pakistan alone there are
glaciers whose total length would add up to above 6,160 sq. km. To
put it more precisely, as high as 37 per cent of the Karakoram area
is under its glaciers against Himalayas' 17 per cent and European
Alps' 22 per cent. The Karakorams have one more claim to proclaim;
its soother flank (east and west of the enormous Biafo glacier) has
a concentration of glaciers which works out to 59 per cent of its
area. There is a historical reason for the fact that we, and the
world outside, are better acquainted with glaciers in the Nanga
Parbat region. It is through this region, hazardous though it is
that man has trudged to and fro since the beginning of his civilized
history of movement and migration. The Siachin glacier is 75 kms.
The Hispar (53 kms) joins the Biafo at the Hispar La (5154.16 meters
(16,910 ft) to form an ice corridor 116.87 kms (72 miles) long. The
Batura, too is 58 kms in length. But, the most outstanding of these
rivers of ice is the 62 kms Baltoro. This mighty glacier fed by some
30 tributaries constitutes a surface of 1291.39 sq. kms.
