| Granite outcrops on a knoll W of and 200m above the Rhone Glacier; bedrock granite exposures have been deeply eroded by cavernous weathering and |
| deflation; the upper rock surfaces however are oxide stained and are hardened and resist erosion; most of the erosion takes place on the rock underside leaving |
| thin oxide stained shells; the question is what is the nature of the case hardening and the surface rock shell |
