Geological subjects: slickenlines on a fault plane
The scale card along the base of the photo is marked in centimetres (black) and millimetres (white bands separated by black lines).
A sub-vertical fault plane with sharp bends and slight curves along slickenline striation paths/traces (in non-technical terms, scratches in the rock from frictional drag along the fault surface),
indicating a history of slight and temporary change in displacement direction (part of Eocene age extensional faulting in south-central British Columbia). Location: Warren Creek Road, near Greenwood, British Columbia.
