This memorandum discusses a potential trigger mechanism for a toppling failure in rock slopes. What is proposed here is not a general case for all toppling failures. It is instead a postulated driving mechanism for slopes meeting specific inherent geometric and geologic conditions. That having been said, these conditions appear to be met in many toppling situations. As the initial trigger phase of the proposed toppling mechanism is easily analyzed, this model may be of use to other slope stability engineers.
