Little tools, big job: The periglacial conveyor system in cryoplanated uplands

چکیده

The mechanisms of sediment removal associated with the nivation process suite are underinvestigated, a situation that hinders development unified, coherent theory cryoplanation terrace formation. This study links sorted stripes—a type periglacial patterned ground frequently encountered on treads—to active hydrologic networks capable transporting large quantities fine sediments hillslopes. Traditional interpretations hold presence indicates geomorphic quiescence, view has contributed to dismissal these features as factor in formation erosional topography. We address role stripes fluvial by investigating their potential for weathered material across and off developing terraces. Flow modeling watershed geomorphometric analyses were conducted using high-resolution digital elevation model geomorphically upland near Atlin, British Columbia, Canada. Results demonstrate landscape-scale spatial organization effectiveness sorted-stripe networks—“little tools”—for water suspended cryoplanated surfaces. present qualitative production transportation, “the conveyor system,” outlines processes responsible defines distinctive hydrologic–geomorphic imprint imparted
