1955 Map of Mt. Sizer

About this map

Henry Willard Coe State Park dominates the high country of the Diablo Range in this mid-century survey, revealing a landscape defined by cattle ranching and early conservation efforts. The map records several established working lands, including Oak Flat Ranch, Los Huecos Ranch, and Coe Ranch, situated along the ridges and valleys between Coyote Creek and the Middle Fork Coyote Creek. The terrain is deeply carved by drainage systems like Vance Canyon and Samson Canyon, leading down to the major reservoirs of Coyote Lake and Anderson Lake. Evidence of localized social and recreational life appears through labels for the Laurel Springs Club and the mineral waters of Madrone Soda Sprs. The complex boundary lines of old Mexican land grants, such as Ojo De Agua De La Coche and San Francisco De Las Llagas, still persist as the underlying cadastral framework of the county.
