Livermore Valley and the Amador Valley meet in this detailed topographic study, showing a region defined by its vital watercourses and early industrial footprint. The landscape is crisscrossed by the Arroyo Mocho, Arroyo Valle, and Arroyo Las Positas, which served as the natural anchors for the burgeoning towns of Livermore and Pleasanton. At this time, the area’s gravel industry was in full swing, evidenced by the extensive Gravel Pits concentrated near Santa Rita.
