1916 Map of Byron Hot Springs

About this map

Byron Hot Springs serves as the focal point of this 1910s era study, situated at the eastern edge of the coastal range where the foothills meet the flatlands of the San Joaquin Valley. This particular survey is unusual for its large Preliminary Edition Unsurveyed Area, leaving much of the western portion blank while providing high-resolution topographic detail for the populated corridor to the east. The settlement of Byron is positioned along the Southern Pacific railroad line, which served as the primary transit artery for the region's agricultural and resort interests. The landscape is defined by the historic land grants of Canada De Los Vaqueros and Los Meganos, with drainage provided by Kellogg Creek and Brushy Creek. The map records the interface between Contra Costa and Alameda counties, capturing the transition from undeveloped ranch lands to the early twentieth-century rail-head economy.
