An aerial photograph shows the features along the abandoned railway line annotated with distance markers, geological features and viewpoints. The geology of the area covers granite of Archean age (older than 2500 million years) and younger dolerite dykes that have intruded the granites. These rocks are exposed on the undulating terrain that forms the edge of the Yilgarn Craton, where this stable block of Western Australia is undergoing weathering.

This product is an A3 map in two sheets written by MJ Freeman in 2017.
