Short summary
Ten years of direct observations of an englacial conduit in a cold based glacier in Svalbard document for the first time how a vertical meltwater waterfall (moulin) is formed from gradual incision of a meltwater channel. This evolution appears to be dominated by knickpoints that incise upstream at rates several times faster than the vertical incision in adjacent near horizontal channel sections.
