epoch are now spread in the form of broad lobes covering immense areas and made
up of vast numbers of conical mounds. In one remarkable instance, a second-
epoch glacier spread all the way across the valley, piling up the slope of its northern
side, just west of the Kashka Su. Through this moraine the Kizil Su has cut a
channel, exposing a section of till resting on alluvium barely above the level of
the stream. This section is of especial importance, for it is clear proof that the
Kizil Su flood-plain was at about the same level there during the second glacial
epoch as it is to-day, and that terraces, which leave the flood-plain about half-
way down the valley and attain a height of 300 feet near its outlet, belong to
some earlier age.
On a visit to the glacier of the Tokuz Kungei, one of the greater Trans-Alai
tributaries to this valley, some ideas were formed about the third and fourth
epochs and their relations to the older. This glacier still terminates piedmont
fashion, deploying—over a massive accumulation of moraine filling the mouth
