About this map

Escalon stands as a primary railroad hub in this San Joaquin Valley landscape, situated at the junction of the Atchison Topeka and Santa Fe and the Tidewater Southern lines. To the northeast, the settlement of Thalheim serves as a secondary nexus where the Southern Pacific tracks bisect a complex network of irrigation infrastructure. This 1913 survey documents the extensive transformation of the arid valley floor into a highly managed agricultural district, defined by the South San Joaquin Irrigation District Canal and a dense system of laterals including the Hirshfeld Lateral and Thalheim Lateral.

The southern boundary of the map follows the winding course of the Stanislaus River, marking the border between San Joaquin and Stanislaus counties. Small, rural community centers are evidenced by the presence of the Lone Tree School, Burwood School, and Langworth School, providing valuable location data for genealogists tracing early 20th-century family homesteads. The vast Thompson Rancho further illustrates the transition from large historical land grants to the smaller, irrigated farm plots characteristic of this era's regional development.
