Yellowman Creek (also Yellowman's) is in the southern Flinders Ranges in the Mount Remarkable area. Murray Town is nearby and the settlement of Melrose lies to the north. It is one of the major tributaries of the Willochra Catchment. The area was used for cropping and grazing from the 1850s. and the creek was named for the bullock of an early settler, Alexander Campbell, which died there (http://www.slsa.ha.sa.gov.au/digitalpubs/placenamesofsouthaustralia/Y.pdf). Like other creeks in the area, it is prone to major flooding after heavy rains necessitating the construction of railway bridges over it and other creeks in the area. The line appears to be the extension from Booleroo Centre to Wilmington, built during WW1 after some years of agitation about the preferred route.

The image, dated 19 September 1917, shows a railway employee in a handcar on the bridge over the creek presumably undertaking inspection or maintenace work.
