Geosphere, October 2011, v. 7, p. 1143-1158, doi:10.1130/GES00594.1, Supplemental Figure 4 - Bedrock exposure showing antislope fault scarp is located along a fault that parallels bedding in the south-dipping limb of the syncline at the Martin Lake trench area. The bedrock is thin-bedded siltstone of the Tokun Formation (Eocene). Unconsolidated colluvium, sag pond deposits, and fluvial sediments deposited by snowmelt runoff are faulted against bedrock on these types of structures.
