Short summary
Examination of recent Google Earth images of glaciers and rock glaciers in the Dry Andes has sufficient detail to show surface meltwater pools. These pools have exposures of glacier ice that core the rock glaciers with volume loss. Such pools are seen on debris-covered glaciers and rock glaciers worldwide and cast doubt on the permafrost origin of rock glaciers.
