Spatial And Temporal Landslide Distribution And Hazard Evaluation Analyzed By Photogeologic Mapping And Relative-Dating Techniques, Salt River Range, Wyoming, John B. Rice Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The distribution of landslide type and age was analyzed to determine the causes and timing of landsliding, and to assess landslide hazards in the study area. 1173 landslides and zones of landsliding were mapped on 1:15,840 scale air photos and designated by their style of movement and age. Slides were assigned to one of four age classes based on their degree of morphologic modification visible on air photos. Relative dating (RD) methods previously applied to glacial deposits were used to refine and calibrate the age classification.

Eleven RD para meters were measured on 21 rockslide and 19 glacial deposits. Cluster …
