This is an irregularly recurring event involving
discharge of water from a supraglacial lake. Catastrophic
discharges, either subglacial or intraglacial,
have initiated significant debris events as the discharge flows downslope through unconsolidated glacial till towards the
railway lines, highway (Trans-Canada) and other structures in the valley
floor.� In 1978, debris flows triggered
by a j�kulhlaup from Cathedral Glacier destroyed
three levels of Canadian Pacific railway track, derailing a freight train. Sections
destroyed three levels of Canadian Pacific railway track, derailing a freight train. Sections of the Trans-Canada Highway were also buried.
