In these pages, Byron Hot Springs historian Carol A. Jensen shares the amazing story of one of California's most dramatic resorts through vintage photography and stories. Drawing from the East Contra Costa Historical Society Resource Room, historical archives, period marketing materials, and private collections, these images tell the complete story of Byron Hot Springs for the first time. Contra Costa native Jensen relates the resort's journey from marshy beginnings through its elegant, taffeta-skirted heyday of the 1910s and 1920s (when it rivaled Hotels Del Monte and Coronado in popularity), to the present-day planning for an anticipated reopening.
