Some Observations on Subglacial Ground-Water flow

Abstract Conduit and regelation water are inferred to drain as ground water from up to 130 km 2 of Columbia Icefield. Subglacial conduits appear to be generally occupied by free surface streams. Ground-water flow will allow exchange between the regelation film and conduits. Present-day discharge fro...

Description
Summary:Abstract Conduit and regelation water are inferred to drain as ground water from up to 130 km 2 of Columbia Icefield. Subglacial conduits appear to be generally occupied by free surface streams. Ground-water flow will allow exchange between the regelation film and conduits. Present-day discharge from beneath the accumulation zone carries little sediment, and past injections of sediment appear to correspond to ancient interglacials. Transport of sediment through cave passages may be analogous to transport through basal conduits.
