1947 Map of Gregg

USGS Topo · Published 1947

About this map

Trigo, Irrigosa, and Gregg represent the quiet agricultural clusters of the San Joaquin Valley shortly after the war, situated along two major rail arteries. The landscape is defined by the intersection of the Southern Pacific and the Atchison Topeka and Santa Fe railroads, which dictated the placement of small settlements and infrastructure in this region of Madera County. Small rural icons like the Sweet Flower Sch and several Windmill sites suggest a community built on localized ranching and farming.
