Translational slides usually fail along geologic discontinuities such as faults, joints, bedding surfaces, or the contact between two rock types. Data. Relentless rain once again this fall and winter at times breaking records is a good reminder that water is heavy, soils get saturated, and gravity wins. The slope material loses strength and runs out, often forming a bowl or depression at the head.
