1977 Map of Lower Lake

About this map

Lower Lake sits at the nexus of the valley floor and rising woodland in this 1977 orthophotograph, which provides a stark visual record of the settlement pattern in Lake County during the late seventies. The aerial imagery captures the distinct grain of the landscape where the agricultural flats of Excelsior Valley meet the drainage of Cache Creek. This specific survey emphasizes the distribution of structures and the clearing of land for residential and agricultural use, contrasting the dense development of the town center against the surrounding vegetation and creek-side terrain. It is a precise baseline for understanding the growth of this interior California community before later modern expansions changed the footprint of the valley floor.
