About this map

Shiloh Basin serves as a central landmark for this portion of Columbia County, where the rural landscape is defined by its networks of timber and water. The map records the local community infrastructure of the early 1970s, including the Shiloh Basin Sch and Shiloh Basin Cem, along with scattered settlements like Trenholm, Canaan, and Merrill. These small hubs are connected by family-named routes such as Nicolai Road and Whitney Road, tracing a pattern of settlement that follows the local drainage systems.

Water management and resource extraction are evident in the presence of the Salmonberry Reservoir and several designated sites for a Quarry and Gravel Pit. The drainage of Goble Creek and the Little Clatskanie River dictates the winding path of the local roads, while the Meissner Lookout at the western edge provides a high-point vantage over the forested terrain. This survey captures a moment before modern development altered the rural character of these upland communities.
