As a severe buran (snow blizzard) blew up and darkened the region, I was
unable to complete my observations on the third and fourth epochs, but it is a
locality worthy of careful exploration.
The glaciers of to-day are of a different character from those about Kara Kul.
To begin with, the snow-line on this side of the Trans-Alai is only about 13,000
feet, and we find true snow-fields—that feature for which the mountains of Kara
Kul are so remarkably in want. There the snow turns to ice as fast as it comes
down; but on this side there is more of it and a less arid sun to transform it. Two
of the present glaciers studied might almost be called piedmont flows. They
descend with a steep grade and spread out fan-shaped upon massive accumulations
of moraine, in part at least belonging to the third epoch (a mass that must be from
1,000 to 2,000 feet in thickness), and spread upon the flat floors they have planed
over these old moraines, to terminate in wide sheets of pinnacled ice, possibly
less than 100 feet in thickness. And these glaciers, like those of Kara Kul, are
