About this map

Jefferson sits at the western edge of this valley landscape, where the North Santiam River and South Santiam River converge amidst a complex network of waterways. The terrain is defined by the broad alluvial plains of McKinney Bottom and Independence Prairie, which are carved by numerous sloughs and ditches including Logan Slough and the Jefferson Ditch. This 2014 survey reveals an agricultural and residential pattern heavily influenced by the seasonal flow of the rivers, with several reservoirs like Wil-Lyn Reservoir and Helms Reservoir managing the water across the basin.

Local landmarks such as Greens Bridge and Sanderson Bridge provide critical crossings over the winding North Santiam and Crabtree Creek. For those researching family history in the area, the map precisely locates the Jefferson Cem and Central Cem. The eastern portion of the quadrangle rises toward the foothills, marked by elevations such as Hungry Hill and the Salem Hills, providing a clear view of the transition from the river bottomlands to the upland reaches of Marion and Linn counties.
