Abstract
⺠Subsurface geologic data documents the distribution of tunnel valleys in NE Alberta. ⺠Tunnel valleys fills comprise multistory, erosion- to succession-dominated deposits. ⺠Deposits reflect allogenic and autogenic controls due to a sequence of jökulhlaups. ⺠Tunnel valley systems evolved time transgressively. ⺠Evolution is in part related to substrate lithology and subglacial hydraulics.
