1957 Map of Greenfield

About this map

Pinnacles National Monument dominates the northeastern landscape of this mid-century survey, revealing the striking volcanic spires and peaks of the Gabilan Range. From North Chalone Peak down to the valley floor, the map documents a transition from protected wilderness to the intensive agricultural development of the Salinas River basin. The town of Greenfield is shown at a point of growth, with its grid of residential streets like Elm Ave and Walnut Ave contrasting with the sprawling ranches and alluvial plains of Llano de los Ositos. The Southern Pacific railroad and Highway 101 serve as the primary conduits for the region's agricultural economy, connecting remote outposts like Metz, Coburn, and Elsa to larger markets. This edition, revised from earlier planetable surveys and aerial photography, captures the early footprint of the Airline Highway and various named homesteads including Sands Ranch and Breen Ranch.
