About this map

Petersburg sits at the nexus of a complex drainage system just south of the Columbia River in this 2011 survey. The landscape is defined by the diverging paths of Fifteenmile Creek, Eightmile Creek, and Fivemile Creek, which carve deep into the plateau. For genealogists, the map is particularly useful for identifying established burial grounds including Petersburg Cemetery, Eightmile Cemetery, and Rice Cemetery, which serve the local agricultural communities.

Tracing the secondary road network reveals how the area is connected by historic routes like Fifteen Mile Rd and the Emerson Loop Rd. In the northwest corner, Memaloose Island and Cushing Falls mark significant points along the river. Notable landmarks such as Columbia Hall and the geographic depression of Japanese Hollow provide specific points of interest for local history researchers mapping out early settlement patterns and social centers.
