History
[edit]Before theCalifornia Gold Rush,theNisenanMaiduoccupied both permanent villages and temporary summer shelters along the rivers and streams that miners sifted, sluiced, dredged and dammed to remove thegold.[6]ExplorerJedediah Smithand a large party of American fur trappers crossed the Sacramento Valley in April 1827. The group saw many Maidu villages along the river banks.[6]Deprived of traditional foodstuffs, homesites and hunting grounds by the emigrants, the Nisenan were among the earliest California Indian tribes to disappear.[6]
During the 1850s, miners sluiced streams and rivers, includingSecret Ravine,which runs through Rocklin. The piles of dredger tailings are still obvious today, between Roseville and Loomis southeast ofInterstate 80.[7]Secret Ravine, at the area now at the intersection of Ruhkala Road and Pacific Street, was later mined for granite, some of which was used as the base course of the California Capitol Building; the earliest recorded use of the rock was for Fort Mason atSan Franciscoin 1855.[8]The granite was hauled out by oxcarts before the arrival of the railroad many years later.[8]
In 1860, the U.S. Census counted 440 residents in the area of Secret Ravine, of whom about 16% had been born inIrelandand the majority of whom worked as miners.[9]The area was referred to as Secret Ravine or the "granite quarries at the end of the tracks" as late as 1864.[9]
Rocklin's history is closely tied to thetranscontinental railroad.In 1862, thePacific Railroad Actgranted theCentral Pacific Railroadland near Secret Ravine.[9]In 1864, theCentral Pacific Railroadcompleted an extension of its track southwest fromNewcastleto Secret Ravine. It named the area Rocklin after its granite quarry and used the site as a refueling andwater stop.The Central Pacific built aroundhousein 1867.[10]The transcontinental railroad was completed in 1869, significantly increasing railroad traffic through the town. According to the 1870 census, Rocklin had grown to 542 residents,[11]and the majority of Irish immigrants had forgone mining and were working for the railroad.[9]In 1908, the Central Pacific moved its facility from Rocklin toRoseville,where more land was available for expansion.[10]The Roseville site has remained in continuous use since. As of August 2014, it is the largest rail facility near the U.S. West Coast.[12]
In 1869, a group of laid-offChinese railroad workersmoved to Secret Ravine to mine and raise vegetables which they sold locally. The Chinese community was violently driven out in September 1876 after a group of Chinese was accused of murdering three people near Rocklin.[13]The area was still known as China Gardens as of 1974.[8]
The Rocklin post office opened in 1868.[14]Finnish immigrants settled in Rocklin starting in the 1870s, and Spanish settlers arriving by way ofHawaiisettled in Rocklin in the early 20th century.[9]The townincorporatedin 1893.[14]
