Santiam State Forest dominates this landscape in the mid-1980s, where the boundary between Clackamas and Marion counties follows the high ridgelines of Gawley Ridge. The terrain is defined by a dense network of timber resources and water management, visible in the numerous Quarry and Borrow Pit sites scattered near Table Rock Road. The northern portion of the map follows the winding course of the Molalla River, which gathers waters from numerous tributaries like Bear Creek and Horse Creek.
