HISTORY The Tatcan and the Volvon are two of the six Bay Miwok-speaking tribes who lived in this area formanygenerations.Whenthefirstnon-Indiansentered Tatcan lands – the 1772 Spanish Fages-Crespí expedition–theTatcanfledfromtheminpanic.Between 1794 and 1804, 271 Tatcans and Volvons became incorporated into the Spanish mission system. Under Mexican governance of California, local tribal people became the primary labor force on large, Mexi-can cattle ranches, including Dona Juana Sanchez de Pacheco’s 17,782-acre Rancho Arroyo de las Nueces y Bolbones(CreekoftheWalnutsandVolvonIndians),which included today’s Diablo Foothills. When James Walker bought part of the rancho in the 1850s, after Californiabecameastate,healsoboughtitsIndianla-borers. From 1902-1940, the William Ford family oper-ated a cattle ranch and dairy at Diablo Foothills. After WorldWarII,amilitaryofficer,andlaterWilliam’ssonRon, operated 230 acres as Castle Rock Park.DESCRIPTION Diablo Foothills offers abundant openlandforhikingandnaturestudy.Its1,060acresare bounded by two dramatic East Bay landforms: the Castle Rocks of Mt. Diablo and the undulating “camel-back” ridges that form Shell Ridge. These ridges link the park to Mt. Diablo State Park and the City of Walnut Creek’s Shell Ridge Open Space, which together, at nearly 22,500 acres, represent one of the largest open space areas of the East Bay. Diablo Foothills also con-tains the 15-acre Castle Rock Regional Recreation Area.NATURAL RESOURCES Vegetation varies from grassland and oak savannah on the hills to riparian and oak woodland in the valley. This creates diverse habitats that support a wide array of wildlife, including mule deer, bobcats, coyote, grey fox, and long-tailed weasels. Birds, such as red-winged blackbirds, northern mock-ingbirds, orioles, and woodpeckers, use the park for nesting and foraging habitat. Rock outcrops shelter gar-ter and gopher snakes, western fence lizards, southern
