Figure 1: Topographic map of the Dry Cirque.
Snowpit locations for chemical samples are designated by diamonds.
The gaging station is marked with a square.
Contour interval is 25 m.
Figure 2: Concentrations of selected ions in the outlet stream of the
Dry Cirque, May 13 to May 19, 1990.
Solute concentrations were inversely related to discharge.
Discharge was separated into snowmelt or new water
and subsurface or old water for the period
May 13 to May 19 using Si as a tracer.

to saturation product (KT) for calcite, dolomite, and gypsum,
as a function of basin area for the
Urumqi River.
