This report describes sand dykes, extensional faulting, and complex deformation of strata as observed in the Kirkpatrick sand & gravel pit located at the north margin of the Fraser Lowland near Maple Ridge, British Columbia. The pit is excavated in a prominent bench of glacial sediments which exposes part of a delta constructed during deglaciation. The report describes the stratigraphic evidence bearing on the origin of the sand dykes and deformation, and discusses possible triggering mechanisms including non-seismic landsliding and earthquake ground shaking.

As a slag heap, the result of strip mining, creeps closer to his house in the Ohio hills, fifteen-year-old M. C. is torn between trying to get his family away and fighting for the home they love.

A well-exposed section about 250 metres wide below the high water line of the Jennings River, Teslin Lake map area in northern British Columbia shows part of the Teslin Fault and provides an opportunity to constrain the fault's kinematic history by direct ground observations. This report describes preliminary structural observations of this section of the Teslin Fault, including the rock types involved, mylonitic & ultramylonitic structures, and deformation. Indications of two main episodes of shearing are discussed.
