About this map

South Lebanon and the rural community of Lacomb anchor this landscape where the South Santiam River and the Lebanon Santiam Canal dominate the southern lowlands. The terrain transitions from the river bottomlands up toward Ridgeway Butte and the foothills of the Cascades, marked by a complex system of ponds and reservoirs such as Mystery Hills Reservoir and Taylor Reservoir. The naming of Onehorse Slough provides a characteristic local identifier for the drainage that winds through the central valley floors.

Evidence of historical settlement and local transit is found in the placement of Providence Cem and Bellinger Cem, alongside rural crossings like Claypool Bridge and Barr Bridge. The presence of the Mt Hope Airport and small settlements like Whitaker and Golden Valley reflect the persistent agricultural and timber-related habitation patterns of Linn County. Wood processing is specifically noted through features like the Western Log Pond and Snow Peak Log Pond, highlighting the industrial heritage of the region.
