Abstract. Recently published work on water preservation in Chile assume that 'permafrost'  (cryogenic) rock glaciers are dominant. Melt pond development shows that rock glaciers are glacier-derived ('glacigenic') rather than of permafrost origin.

Short summary
Examination of recent Google Earth images glaciers and rock glaciers in the 'Dry Andes' have 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.
