abstract
It was noted that exiting water had higher ion concentrations than entering forms; water input had total dissolved loads ranging from 1.5 to 6.0 mg l-1, whereas outputs had total dissolved loads ranging from 8.0 to 54.0 mg l-1; silica concentrations ranged from 0-0.1 mg l-1in inputs to 1.9-6.0 mg l-1in outputs; alkalinity values for inputs ranged from 1.3 to 2.7 mg l-CaCO3, whereas outputs ranged from 18.1 to 44.4 mg l-1CaCO3; and total hardness values for inputs were 0.0 mg l-1CaCO3, whereas outputs ranged between 21.0 and 50.1 mg l-1CaCO3. Water flowing through three rock glaciers decreased in pH. Inputs into the rock glaciers had pH values ranging between 6.4 and 7.0, whereas outputs had pH values ranging between 7.2 and 8.5. Peak discharge of the three rock glaciers occurred between 0900 and 1200 hours daily, before daily maximum temperature occurred. -from Authors
