About this map

The Klamath River carves a deep canyon through this high-elevation landscape on the border of Oregon and California during the mid-1980s. Hydroelectric development is central to the area, anchored by the John C Boyle Reservoir and the John C Boyle Powerplant located near the river's sharp Big Bend. These facilities represent the mid-century industrial push to harness the river's power along the rugged transition from the Cascades to the Klamath Basin.

Evidence of earlier human presence is found at the Topsy (Site), located along the historic Topsy Road. The map details a varied terrain of volcanic peaks and high flats, from Hayden Mtn in the northwest to the Chicken Hills in the east. Forestry and water management are reflected in the presence of the Penny Spring Guard Sta and numerous named springs, while the southern portion of the sheet transitions into the Klamath National Forest.
