{"Image DocumentName": "THE GOLD RUSH", "Image ImageDescription": "January 1848: James W. Marshall was building a sawmill on the American River in Sacramento Valley east of San Francisco when he noticed flecks that turned out to be GOLD! Created international sensation.  200 million was extracted in next 4 years. By summer of 1848 San Francisco had become a virtual ghost town and two-thirds of the adult males in Oregon had headed to the California gold fields. During 1849, 25,000 Americans made their way from the east to California by ship. 55,000 crossed the continent by overland routes. 8,000 Mexicans, 5,000 South Americans and a number of Europeans joined the rush. Between 1849 and 1860 about 200,000 people (nearly all males) crossed the Rockies to California and thousands more came by ship.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
