About Rocklin

Rocklin is a city in Placer County, California, about 22 miles (35 km) from Sacramento, and about 6.1 miles (9.8 km) northeast of Roseville in the Sacramento metropolitan area. Besides Roseville, it shares borders with Granite Bay, Loomis and Lincoln. As of the 2020 census, Rocklin's population was 71,601. == 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. 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. Deprived of traditional foodstuffs, homesites and hunting grounds by the emigrants, the Nisenan were among the earliest California Indian tribes to disappear.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. 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. The granite was hauled out by oxcarts before the arrival of the railroad many years later.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.
