Rocklin is a city in Placer County, California located approximately 22 miles (35 km) from Sacramento, California, and about 6.1 miles (9.8 km) northeast of Roseville in the Sacramento metropolitan area. Besides Roseville, it shares borders with Loomis, and Lincoln. As of the 2010 census, Rocklin's population was 56,974.


Prior to the California Gold Rush the Nisenan Maidu occupied permanent villages and temporary summer shelters along the rivers and streams the miners sifted, sluiced, dredged and dammed to remove the gold.[4] Explorer Jedediah Smith and a large party of American fur trappers crossed the Sacramento Valley in late April, 1827. The group saw many Maidu villages on the river banks.[4] Deprived of traditional foodstuffs, homesites and hunting grounds by the emigrants, the Nisenan were among the earliest California Indian tribes to disappear.[4]

During the 1850s, miners sluiced streams and rivers including Secret Ravine which runs through Rocklin. The piles of dredger tailings is still obvious today, between Roseville and Loomis southeast of Interstate 80.[5] 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 in Sacramento, although the earliest recorded use of the rock was for Fort Mason at San Francisco in 1855.[6] The granite was hauled out by ox carts before the arrival of the railroad many years later.[6]

In 1860, the U.S. Census counted 440 residents in the area of Secret Ravine of which about 16% were born in Ireland the majority of whom worked as miners.[7] In 1863-4, the Central Pacific Railroad built a line up to Newcastle and named the town Rocklin after the quarries in the area. Prior to the arrival of the railroad the area was referred to as Secret Ravine or the "granite quarries at the end of the tracks" as late as 1864.[7]

The Rocklin post office opened in 1868.[8] In 1869 some laid-off Chinese railroad workers moved to Secret Ravine to mine and raise vegetables to sell locally.[6] They were driven out during the anti-Chinese pogrom of September 1876 but the area is still known as China Gardens.[6] The 1870 census shows that the Irish had given up on mining and were working for the railroad.[7] Finnish settled in Rocklin starting in the 1870s, and Spanish settlers arriving by way of Hawaii in the early 20th Century.[7] The town incorporated in 1893.[8]


Rocklin is located at 38°48′00″N 121°14′48″W / 38.800011°N 121.246731°W / 38.800011; -121.246731.[9]

According to the United States Census Bureau, the city has a total area of 19.6 square miles (51 km2), of which 0.05 square miles (0.13 km2), or 0.27%, is water.
