About this map

Onehorse Slough winds through the foothills of the Cascade Range, providing a drainage network that defines the agricultural and timber landscape of this portion of Linn County. This 2014 survey reveals a transition from the valley floor settlements like South Lebanon and Golden Valley toward the more elevated terrain near Ridgeway Butte. The map documents the persistent timber industry infrastructure, shown through features such as the Snow Peak Log Pond and Western Log Pond.

Genealogists and local historians can locate established community landmarks, including the Providence Cem and Bellinger Cem, as well as the small aviation hub at MT Hope Airport. The hydrological complexity of the region is evident in the Lebanon Santiam Canal and the South Santiam River at the southern edge, while historical crossings such as Claypool Bridge and Barr Bridge provide clear reference points for those tracing old family property lines or road developments in the Lacomb area.
