1965 Map of Knob Hill

About this map

Mt Poso Oil Field dominates this central California landscape, revealing an industrial footprint defined by pipelines, oil sumps, and gaging stations. The terrain is deeply incised by a series of drainages, including Granite Canyon, Adobe Canyon, and Borel Canyon, which flow toward the perennial course of Poso Creek. Significant landmarks like the Halfway House and the summit of Knob Hill provide navigational anchors in an area where the petroleum economy and topography intersect. To the south, the Round Mtn Oil Field extends into the territory near Coffee Canyon, illustrating the extensive reach of mid-century energy extraction. Geologic and geographic transitions are marked by features such as Chalk Cliff and Mon Bluff, while the presence of scattered water tanks and wells underscores the infrastructure required to sustain operations in this arid environment.
