Recent archaeological evidence indicates earliest human habitation of the Rocklin area at about 7,000 years ago. About 3000 year ago, perhaps as late as 1500 years ago, the Nisenan, sometimes called Southern Maidu, arrived to occupy the area. Although European-Americans severely disrupted their culture in the 19th century, descendants of these people still reside in South Placer County.
Although European-Americans were probably fishing and harvesting game in the Rocklin area in the late 18th and early 19th Centuries, major European-American settlement started in the early 1850’s as fortune hunters sluiced for gold in Secret Ravine, an area of oaks and dredger tailings that can be found today southeast of Interstate 80 between Roseville and Loomis.
