摘要：
A study of the 68-mi section of the canyon between Lytton and Hope, along the Canadian National Railway, was made to determine what factors controlled slope stability on a regional scale. Engineering geology aspects concerning regional faulting and related minor structure, lithology, drainage and hydrology, geomorphology, climate, river geometry, and effects of man were considered. The most significant cause of slope instability was deflecting of the Fraser River into its bank by the presence of either an alluvial fan at a tributory mouth or a river bend. This deflection allowed extensive lateral erosion and resulted in severe oversteepening, which undermined the toe of the slope.
