The Clackamas River watershed in the mid-1950s is defined by its deep canyons and early mid-century forest infrastructure. The hydroelectric developments near Three Lynx and Whitewater are prominent, featuring a Powerhouse, a Surge Tank, and a Pipeline system that reflects the era's focus on river power. This rugged interior of Clackamas County was managed through a network of guard and ranger stations, including the North Fork Guard Sta and Oak Grove Ranger Sta.
