History

Before the California Gold Rush, the Nisenan Maidu occupied both permanent villages and temporary summer shelters along the rivers and streams that miners sifted, sluiced, dredged, and dammed to remove the gold.<ref name ="FHM">Template:Cite web</ref> Explorer Jedediah Smith and a large party of American fur trappers crossed the Sacramento Valley in April 1827. The group saw many Maidu villages along the river banks.<ref name ="FHM" /> Deprived of traditional foodstuffs, homesites, and hunting grounds by the emigrants, the Nisenan were among the earliest California Indian tribes to disappear.<ref name ="FHM" />

During the 1850s, miners sluiced streams and rivers, including Secret Ravine, which runs through Rocklin. The piles of dredger tailings are still obvious today, between Roseville and Loomis southeast of Interstate 80.<ref>Introduction to Rocklin History Series</ref> 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 at San Francisco in 1855.<ref name = "Ruhkala">Template:Cite web</ref> The granite was hauled out by oxcarts before the arrival of the railroad many years later.<ref name = "Ruhkala" />

In 1860, the U.S. Census counted 440 residents in the area of Secret Ravine, of whom about 16% had been born in Ireland and the majority of whom worked as miners.<ref name="Day">Template:Cite web</ref> The area was called Secret Ravine or the "granite quarries at the end of the tracks" as late as 1864.<ref name ="Day" />

Rocklin's history is closely tied to the transcontinental railroad. In 1862, the Pacific Railroad Act granted the Central Pacific Railroad land near Secret Ravine.<ref name ="Day" /> In 1864, the Central Pacific Railroad completed an extension of its track southwest from Newcastle to Secret Ravine. It named the area Rocklin after its granite quarry and used the site as a refueling and water stop. The Central Pacific built a roundhouse in 1867.<ref name="Day_roundhouse">Template:Cite web</ref> The transcontinental railroad was completed in 1869, significantly increasing railroad traffic through the town. According to the 1870 census, Rocklin had 542 residents,<ref name="Hist">Template:Cite web</ref> and the majority of Irish immigrants had forgone mining and were working for the railroad.<ref name ="Day" /> In 1908, the Central Pacific moved its facility from Rocklin to Roseville, where more land was available for expansion.<ref name="Day_roundhouse" /> The Roseville site has remained in continuous use since. As of 2014, it was the largest rail facility near the U.S. West Coast.<ref name='uprr'>Template:Cite web</ref>

In 1869, a group of laid-off Chinese railroad workers moved to Secret Ravine to mine and raise vegetables, which they sold locally. The Chinese were violently driven out in 1876 after a group of them were accused of murdering three people near Rocklin.<ref>Pfaelzer, Jean, Driven Out: The Forgotten War Against Chinese Americans, 83-85 Random House New York 2007.</ref> The area was still known as China Gardens as of 1974.<ref name = "Ruhkala" />

The Rocklin post office opened in 1868.<ref name=CGN>Template:California's Geographic Names</ref> Finnish immigrants settled in Rocklin starting in the 1870s, and Spanish settlers arriving by way of Hawaii settled in Rocklin in the early 20th century.<ref name ="Day" /> The town incorporated in 1893.<ref name=CGN/>
