With the decline of coal mining some residents turned to ranching. Later rich deposits of sand were mined for glass and foundry use. In 1973, the East Bay Regional Park District acquired the land. Today visitors to Black Diamond Mines Regional Preserve, located 45 miles east of San Francisco, can explore miles of trails, tour the Hazel-Atlas silica sand mine, and visit historic Rose Hill Cemetery.\u003c\/p\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003eNumber of Pages:\u003c\/strong\u003e 130\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.38 x 9.61 x 6.69 IN\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003ePublication Date:\u003c\/strong\u003e February 25, 2009\u003c\/div\u003e\n            ","brand":"BooksCloud","offers":[{"title":"Default Title","offer_id":52625515479347,"sku":"9781531645939","price":41.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0300\/5595\/6612\/files\/bVUvQTIzSGdYNktwaGlOWGltZVFGQT09.webp?v=1762045067","url":"https:\/\/www.vysn.com\/products\/black-diamond-mines-regional-preserve-hardcover","provider":"VYSN","version":"1.0","type":"link"}
