Geology of Portage Mountain Damsite, Peace River, B.C.
Portage Mountain site was chosen specifically because it is on secure, massive, relatively impermeable sandstone beds of Cretaceous Dunlevy formation; beds dip gently downstream, and faults are absent; intercalated shales are of noncompaction type and present only minor problems to construction; interbedded coal seams present, essentially, only grouting problem; dam will be constructed of gravels obtained from glacial moraines.
