Geology
Geological setting:
Local rocks are granites and gneiss but till covers the lower slopes and includes some dolerite and sandstone
Patterned ground:
Weakly developed broad nets; possible solifluction lobes on steeper slopes
Surface weathering or surface features:
Some larger rocks spalling and moving apart by ice wedging; many rocks are moderately stained and partly rounded; granular disintegration and pitting, cavernous weathering and ventiforms are negligible; non pavementic
Patchy snow cover from recent fall with thawing at edges and localized soil moistening
Biological activity:
Nil observed
