The town of Byron and the nearby resort at Byron Hot Springs anchor this 1911 survey of eastern Contra Costa County. Surveyed by Duncan Hannegan and J. L. Lewis under the direction of George Otis Smith and State Engineer Nathaniel Ellery, this advance sheet highlights the transition from the developed railroad corridor to the complex topography of the Canada De Los Vaqueros. The map illustrates early water management along Marsh Creek, which winds through the northwestern corner of the quadrangle. For researchers of early California leisure and land use, this sheet documents the specific layout of the famous hot springs at a time when the mineral waters were a premier destination for those traveling by rail through the San Joaquin Valley.
