1972 Map of Unity Reservoir

USGS Topo · Published 1976

About this map

Unity Reservoir dominates the southern landscape of this Baker County quadrangle, where the Burnt River and its various forks converge. The 1970s terrain is defined by the sharp transition from the irrigated valley floors and the waters of the reservoir to the high timbered slopes of the Whitman National Forest. Evidence of early industry and water management persists through labels like Martins Mill and the extensive network of irrigation infrastructure including the Ditch systems and a Siphon near the river banks. Along the Dooley Highway, the landscape reflects a mix of ranching life at the King Ranch and public recreation at the Unity Lake State Park campground. Small family-scale details, such as the lonely Cem on a ridge overlooking Pine Creek, provide essential clues for genealogists tracking early settlers in this high-desert mountain region.
