The California city of Folsom is located in Sacramento County, about 22 miles northeast of the state capital of Sacramento. A large network of area freeways encompasses the city, and these include Interstate I-80 and U.S. Route 50. Surrounding communities include Loomis (to the north), Carmichael (to the west), Rancho Cordova (to the southwest), and El Dorado Hills (to the east).
Folsom traces its origins to the mid-nineteenth century, when gold was discovered in the area and massive mining operations were set up. At the conclusion of the Mexican-American War, U.S. Army Captain Joseph Folsom purchased 35,000 acres of land and planned a town site near one of the mining spots. Envisioning the site as a future railroad stop, Folsom named the new town "Granite City". His vision was realized posthumously in 1856 when the first train on the West's first railroad arrived in the town from Sacramento. Subsequently, Folsom's successors renamed the town in his memory and several decades later, construction began on Folsom Prison. The facility, designed to relieve over-crowding at San
Quentin, opened in 1880. Folsom made history in 1895 when the first long-distance transmission of electricity (22 miles) was made from Folsom to Sacramento.
