What factors played a role in the tragic rock slide at Frank, Alberta, Canada, in 1903? What will be an ideal response?
Although many of the rocks on Turtle Mountain dip away from the valley, the joints in the massive
limestone composing Turtle Mountain dip steeply toward the valley, so they are parallel with the
mountain's slope. The rocks are weak limestones, shales, and coal layers that underwent slow plastic
deformation from the weight of the overlying limestone. Coal mining along the base of the valley
removed some of the underlying support. Frost action and chemical weathering widened the joints, and
a rock slide resulted.
