Two case histories describe instances in which operating pipelines have experienced stress or failure as a result of slope instability. Factors which led to pipeline distress and remedial actions in two actual cases are discussed in this second of two articles on pipeline terrain. Both sites are located very near each other within the west central area of Alberta. Each case history is unique, as were the remedial measures adopted to ensure pipeline integrity. This article is divided into the following areas: Early evidence; Spring thaw; Partial collapse; Another washout; Remediation; Simonette river; Northern slope site; Continued movement; Continued monitoring; and Global positioning survey.
