with the upbuilding, especially at high altitudes, which, as mentioned before, induces
Professor PENCK to discuss the existence of an »upper denudation limit», above which
no mountains are supposed to rise. That the Gurla Glacier retreats at the same
time that the Garhwal passes are more snow-covered than formerly, depends upon local
causes. The channel of Manasarovar is a useful control. When it is dry very likely
the surrounding glaciers soon will begin to retreat. But the information that the
Garhwal passes now are more difficult than in earlier days, cannot be used for scientific
purposes. The change may simply depend on a deterioration of the natives in the
surrounding regions, and a decline of the enterprising spirit.
