Melt water streams of the McMurdo Dry Valleys connect glaciers to lakes carrying dilute glacial melt water that exchanges through streambed sediments dissolving them very rapidly.

Comparison of published silica weathering rates for several watersheds in the continental United States, separated by main bedrock mineral, and the bulk weathering rate from studies in the McMurdo Dry Valleys, Antarctica (MCM LTER). Note the log scale of the y-axis.
